Why is my Cat Drooling?

Understanding Cat Drooling

The Basics of Feline Salivation

Salivation is a normal physiological process in cats, essential for maintaining oral health and aiding in digestion. Cats produce saliva through salivary glands, which serve several functions, including lubricating food, protecting the mouth's mucous membranes, and initiating the breakdown of starches.


  • Lubrication: Saliva moistens food, making it easier to swallow.
  • Protection: It helps to protect the mouth's lining and teeth from irritants and decay.
  • Digestion: Enzymes in saliva begin the digestive process.


While drooling is often associated with issues in cats, it's important to remember that mild, infrequent drooling can be perfectly normal, especially when your cat is relaxed or has encountered a particularly appetizing scent or flavor.


Common Reasons for Drooling in Cats

Cats may drool for a variety of reasons that are typically benign, but sometimes they can signal underlying health issues. Understanding the context and frequency of your cat's drooling is crucial in determining whether it's a cause for concern.


  • Happiness or Contentment: Just like humans, cats can drool when they're feeling particularly relaxed or happy, often during petting or cuddling sessions.
  • Nausea or Anticipation: Drooling can occur in response to the smell of food, or if the cat is feeling nauseous.
  • Dental Issues: Oral diseases, such as gingivitis or periodontal disease, can cause drooling. It's important to monitor for other signs of dental problems.
  • Medications: Certain medications may induce drooling as a side effect.


It's essential to observe if the drooling is accompanied by other symptoms, such as bad breath, loss of appetite, or changes in behavior, which could indicate a more serious condition.


Distinguishing Between Normal and Abnormal Drooling

Understanding when your cat's drooling is a sign of contentment or a signal of distress is crucial for their well-being. Normal drooling is often sporadic and occurs in situations where your cat is relaxed or encountering something pleasurable, like their favorite treat or during a comforting petting session.


However, abnormal drooling can be a symptom of underlying issues and is usually accompanied by other signs of distress or illness. It's important to observe your cat's overall behavior and physical condition to determine the cause of excessive salivation.

Consistent or heavy drooling, especially if paired with changes in behavior or eating habits, warrants closer attention and possibly a vet visit.


Here's a quick reference list to help you distinguish between the two:


  • Normal Drooling: Occasional, linked to pleasure or relaxation.
  • Abnormal Drooling: Persistent, may include bad breath, pawing at the mouth, or reduced appetite.
  • Action: Monitor and consult a vet if abnormal signs persist.


Normal Drooling Scenarios

During Relaxation and Petting

Many cat owners notice that their feline friends may start to drool when they are in a particularly relaxed state or while being petted. This is generally a sign of contentment and can be compared to a person's sigh of relief. When your cat is purring and kneading, a little drool is not uncommon and is typically no cause for alarm.


  • Purring: A sign of happiness and relaxation.
  • Kneading: Often accompanied by drooling, indicates comfort.
  • Closed or half-closed eyes: Suggests your cat is in a state of trust and pleasure.


It's important to observe the context in which your cat drools. If it occurs exclusively during these serene moments, it's likely just a natural response to feeling safe and loved. However, if drooling is persistent or accompanied by other symptoms, it may warrant further investigation.


Response to Tasty Food or Medication

Cats may drool in anticipation of or while enjoying a particularly appetizing meal. This is a natural reflex, similar to how humans might salivate when thinking about a favorite food. The presence of drool in these instances is typically a sign of a healthy appetite and pleasure.


Certain medications can also induce drooling as a side effect. This is often temporary and should subside once the medication has been fully ingested or its effects wear off. Below is a list of common medications that may cause drooling in cats:


  • Anti-inflammatory drugs
  • Deworming treatments
  • Sedatives
  • Bitter-tasting medications


It's important to monitor your cat's reaction to new medications and consult your vet if drooling persists or is accompanied by other symptoms.


Teething in Kittens

Just like human babies, kittens go through a teething phase that can cause them to drool. This is a normal part of their development as they lose their baby teeth and their adult teeth come in. Kittens typically begin teething at around 2 to 4 weeks of age, and the process can continue until they are about 6 months old.


During this time, you may notice your kitten drooling more than usual or chewing on objects to relieve the discomfort. To help your kitten through this phase, consider providing teething toys that are safe and designed for kittens.

It's important to monitor your kitten's teething process to ensure that teeth are coming in correctly and there are no complications.


If you observe excessive drooling or if your kitten seems to be in pain, consult your veterinarian. They can provide guidance and, if necessary, treatment to make your kitten's teething experience as comfortable as possible.


Causes of Concern in Cat Drooling

Dental Disease and Oral Pain

One of the most common reasons for a cat to drool excessively is due to dental disease or oral pain. Periodontal disease, which affects the gums and structures supporting the teeth, can lead to significant discomfort and drooling. Other dental issues such as cavities, gingivitis, or tooth resorption can also cause a cat to drool.


Symptoms of dental disease in cats may include bad breath, difficulty eating, and visible tartar on the teeth. If you notice any of these signs, it's important to consult your veterinarian. They can provide a proper diagnosis and treatment plan to alleviate your cat's discomfort.

Early detection and treatment of dental issues are crucial in preventing more serious health problems and ensuring your cat's well-being.


  • Bad breath
  • Drooling
  • Loss of appetite
  • Pawing at the mouth
  • Visible tartar or tooth discoloration


These symptoms should not be ignored as they can indicate a more serious underlying condition that may require immediate attention.


Signs of Illness or Poisoning

Drooling can be a telltale sign that your cat is experiencing more than just a minor nuisance. When drooling is accompanied by other symptoms, it may indicate illness or poisoning, which requires immediate veterinary attention. Cats are curious by nature, and they may ingest toxic substances that lead to excessive salivation.


Symptoms to watch for include:


  • Vomiting or diarrhea
  • Lethargy or weakness
  • Changes in drinking or eating habits
  • Difficulty breathing
  • Sudden changes in behavior


If your cat exhibits any of these symptoms along with drooling, it's crucial to seek veterinary care as soon as possible. Early detection and treatment can be lifesaving.


Remember, not all drooling is a sign of distress, but it's better to err on the side of caution. Keeping potential toxins out of reach and monitoring your cat's behavior are key to ensuring their well-being.


Foreign Objects and Trauma

Cats are curious creatures, and their exploration can sometimes lead to injuries or the ingestion of foreign objects. Trauma to the mouth or the presence of an object lodged in the gums or throat can cause excessive drooling. It's crucial to be aware of the signs that may indicate your cat has encountered such an issue.


  • Sudden onset of drooling
  • Pawing at the mouth or face
  • Difficulty eating or refusing food
  • Visible distress or pain
  • Unusual mouth odor or bleeding


If you notice any of these symptoms, it's important to act quickly. Gently open your cat's mouth to look for any visible foreign objects, but be cautious as cats in pain may bite. If you cannot easily remove the object or if your cat continues to show signs of distress, seek veterinary assistance immediately.

Diagnosing Excessive Drooling

When to Visit the Vet

Identifying the right time to seek professional help for your cat's drooling can be crucial. If your cat's drooling is accompanied by other concerning symptoms, such as a lack of appetite, vomiting, or lethargy, it's time to visit the vet. Immediate attention is especially important if the drooling is sudden and profuse, as it could indicate a serious underlying condition.


It's better to err on the side of caution and consult with a veterinarian if you notice any changes in your cat's drooling patterns or general behavior. Remember, prompt action can make all the difference.


If you're unsure whether your cat's symptoms warrant a vet visit, consider the following points:


  • Is the drooling persistent or intermittent?
  • Are there any changes in eating or drinking habits?
  • Does your cat show signs of discomfort or pain?
  • Have you noticed any foreign objects in your cat's mouth?


In case of an emergency, having the contact information for an emergency vet orillia at hand can provide peace of mind and allow for quick action.


What to Expect During the Examination

When you bring your cat to the vet for excessive drooling, the examination will be thorough to pinpoint the cause. Your vet will start with a physical examination, checking for any signs of oral discomfort, swelling, or other abnormalities. Expect your cat's mouth to be examined for dental issues, lesions, or foreign objects.


The vet may also perform a series of diagnostic tests to further investigate the symptoms. These tests can include:

  • Bloodwork to assess overall health
  • Urinalysis to check kidney function
  • X-rays or ultrasounds to look for internal issues


If necessary, your vet will utilize a Complete In-House Laboratory to get quick and accurate results. This allows for a faster diagnosis and immediate commencement of treatment if required.


Remember, the goal of the examination is to ensure your cat's health and comfort. Your vet is equipped to handle the situation with care and professionalism, aiming to relieve any discomfort your cat may be experiencing.


Possible Tests and Treatments

Once your vet has conducted a thorough examination, they may suggest a series of tests to pinpoint the cause of your cat's excessive drooling. Bloodwork and urinalysis are common starting points to assess overall health and organ function. Depending on the initial findings, more specific tests like X-rays or an ultrasound may be necessary to look for abnormalities in the mouth or abdomen.

Additional diagnostic tools may include:


  • A complete blood count (CBC)
  • Biochemical profile
  • Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) tests


Treatment will vary based on the diagnosis. Dental issues may require cleaning or extractions, while systemic illnesses could need medication or more complex interventions. In cases of poisoning, immediate detoxification is critical. Your vet will provide a tailored treatment plan to ensure the best outcome for your feline friend.


Prevention and Care for Drooling Cats

Maintaining Dental Hygiene

Maintaining proper dental hygiene is crucial for preventing many causes of drooling in cats. Regular dental check-ups and cleanings are essential to ensure your cat's teeth and gums remain healthy. At home, you can support your cat's dental health by following these steps:


  • Provide dental-friendly toys and treats that help reduce plaque and tartar build-up.
  • Brush your cat's teeth regularly with a vet-approved toothpaste.
  • Inspect your cat's mouth periodically for signs of redness, swelling, or bad breath.


Early detection and treatment of dental issues can significantly reduce the risk of severe health problems and excessive drooling. It's important to familiarize your cat with dental care routines from a young age to minimize stress and resistance during teeth cleaning sessions.


Monitoring for Potential Hazards

Keeping your cat safe from potential hazards that can cause excessive drooling is an essential aspect of pet care. Regularly inspect your home and remove any items that could be harmful if chewed or swallowed. This includes houseplants, small objects, and toxic substances.


  • Houseplants: Many common houseplants are toxic to cats. Keep these out of reach or avoid them altogether.
  • Small Objects: Cats are curious and may play with or ingest small items. Regularly check for and remove these hazards.
  • Toxic Substances: Ensure all chemicals and medications are securely stored away from your cat's reach.

By being vigilant and proactive, you can minimize the risk of your cat encountering something that could lead to drooling due to irritation or poisoning. It's also important to be aware of the signs of distress in your cat, such as sudden changes in behavior or appetite, which could indicate they've come into contact with a hazardous substance.


Managing Chronic Conditions

Chronic conditions in cats, such as kidney disease or hyperthyroidism, can sometimes lead to increased drooling. Managing these conditions is crucial to reduce drooling and improve your cat's quality of life. Regular check-ups with the vet and adhering to prescribed treatments are essential.

  • Monitor your cat's overall health and behavior for changes.
  • Ensure consistent administration of medications.
  • Keep a record of symptoms, including any instances of cat coughing or changes in drooling patterns.

It's important to work closely with your veterinarian to adjust treatments as necessary and to keep chronic conditions under control. This proactive approach can help minimize drooling and other symptoms, providing your cat with the best possible care.

How to Remove a Tick from a Dog (Tick Removal & Prevention Tips)

September 26, 2024
If you’ve ever owned a cat, you’ve probably experienced those moments when your feline friend suddenly starts licking you. While it can be sweet and endearing, you might wonder, "Why does my cat lick me?" Licking is a complex behaviour in cats, often connected to communication, grooming, or bonding. Understanding why your cat exhibits this behaviour can help in Behaviour Management and strengthen your relationship with your furry companion. In this blog, we’ll explore some common reasons cats lick their owners, what it means, and when it may be worth visiting your local Orillia vet . 1. Bonding and Affection One of the primary reasons cats lick their owners is to show affection. Cats groom one another as a way of bonding, and when they lick you, they may treat you like one of their family. This behaviour is especially common in cats that were socialized with humans from a young age. If your cat frequently licks you, they say, "I trust you, and you’re part of my family." Grooming is a significant aspect of how cats communicate affection within their social group, and as a cat parent, you’re included in that! So, when your cat licks you, think of it as their unique way of hugging you. 2. Marking Territory Cats have scent glands around their mouth, and licking is another way to mark their territory. When your cat licks you, they might leave their scent on you to claim ownership. This is part of their natural territorial behaviour, and it can be seen as a compliment—it means they feel secure enough around you to mark you as "theirs." This behaviour often ties back to how cats manage their environment and relationships. Proper Behaviour Management can help redirect this behaviour if it becomes excessive, especially if you feel overwhelmed by constant licking. One effective Behaviour Management technique to discourage excessive licking is redirection with a positive alternative . If your cat begins to lick you excessively, gently distract them with a toy or a treat, redirecting their focus onto something more appropriate. You can also use interactive toys like feather wands or puzzle feeders to engage their natural hunting instincts, which may reduce the urge to lick. For example, when your cat starts licking you, gently move them to a different area, offer them a toy, and praise them when they engage with the new object. This positive reinforcement helps them associate their attention with the toy instead of you, gradually reducing the licking behaviour. 3. Seeking Comfort and Security Licking can also serve as a self-soothing behaviour for cats. Much like how kittens nurse and groom themselves or their siblings for comfort, adult cats may lick their owners when anxious or stressed. If your cat has been in a stressful situation—like moving homes or after a visit to the Orillia vet —they may lick you more frequently to seek comfort. If your cat seems more anxious than usual, monitoring their behaviour and environment can help. Offering them a quiet space or using stress-relief products designed for cats can help alleviate this behaviour. If you notice this behaviour becoming compulsive, it might be worth consulting with your vet about possible underlying issues. 4. Mimicking Motherly Instincts Mother cats spend significant time grooming their kittens to keep them clean and show affection. Adult cats may carry over this behaviour into their human relationships by licking you as a way of mimicking their mother’s nurturing instincts. This is especially common in cats who were separated from their mother too early, as they may develop strong grooming habits that they apply to their human companions. While this behaviour is often harmless, it's a good idea to ensure your cat has plenty of opportunities to groom itself or objects around the house. Providing safe, textured surfaces or grooming toys can help balance their grooming needs. 5. Exploration and Curiosity Cats are naturally curious creatures, often using their mouths and tongues to explore new textures or tastes. If you’ve just applied lotion or have a unique scent on your skin, your cat may lick you out of sheer curiosity. This can be their way of investigating something new in their environment. Although occasional licking for curiosity is normal, make sure to keep harmful substances, such as strong chemicals or products that are toxic to cats, out of your cat's reach. A quick trip to your Orillia vet is highly recommended if your cat accidentally ingests something harmful. When to Be Concerned While licking is often a normal behaviour for cats, excessive licking can indicate an underlying issue, such as anxiety, allergies, or nutritional deficiencies. If you notice your cat licking you or themselves excessively, look for other signs like hair loss, weight changes, or changes in appetite. In some cases, licking may expose your cat to toxic substances, especially if they've come into contact with harmful chemicals or products. This risk is particularly high for small kittens, whose small size makes them vulnerable to toxic effects. Signs of poisoning in cats may include: Vomiting Diarrhea Lethargy or weakness Drooling or foaming at the mouth Tremors or seizures Rapid breathing or difficulty breathing Lack of coordination If you suspect your cat or small kitten has licked something poisonous, seeking immediate veterinary attention is crucial. Time is of the essence, as symptoms can escalate quickly in smaller cats. A quick visit to Pine Grove Veterinary Hospital can help ensure the proper treatment is provided to prevent serious complications. Consulting with a vet can help determine whether there’s a medical or behavioural cause behind the excessive licking. They can provide personalized guidance on managing the behaviour and addressing health concerns. Conclusion So, why does your cat lick you? It could be a variety of reasons—affection, marking territory, seeking comfort, or just plain curiosity. In most cases, licking is a normal and healthy behaviour, showing your cat’s bond with you. However, if the behaviour becomes excessive, it may be time to consider some Behaviour Management strategies or consult with Pine Grove Veterinary Hospital to ensure your cat is happy and healthy.  Understanding your cat’s behaviour helps build a stronger connection with them, ensures their well-being, and makes you and your furry friend much happier.

As a pet owner, you never know when your furry companion may need urgent medical attention. Whether it's a sudden illness, an accident, or an unexpected reaction to something, having access to an emergency vet in Orillia can make all the difference in a critical situation. Pet emergencies can be stressful, and knowing you have a trusted professional on speed dial provides peace of mind and ensures your pet receives the care they need as quickly as possible. In this blog, we’ll explore the benefits of having an emergency vet readily available, what to expect from a fear-free vet experience, and how Preventive Care plays a crucial role in reducing the risk of emergencies. 1. Immediate Access to Life-Saving Care One of the most significant benefits of having an emergency vet in Orillia on speed dial is the ability to access immediate medical care when your pet’s health is in jeopardy. Emergencies can happen anytime—often after hours when regular veterinary clinics are closed. From injuries and trauma to sudden illnesses or severe allergic reactions, an emergency vet is trained to handle these urgent situations and provide life-saving interventions. If your pet is experiencing symptoms like difficulty breathing, uncontrolled vomiting, seizures, or has been involved in an accident, every minute counts. Having an emergency vet's contact information ready ensures you can act swiftly, potentially saving your pet’s life. 2. Stress-Free, Fear-Free Vet Experience Many pets experience anxiety during vet visits, which can be exacerbated in an emergency. The concept of a fear-free vet at Pine Grove Veterinary Hospital focuses on minimizing your pet’s stress and anxiety during medical visits. Fear Free-certified veterinary professionals use specialized techniques to make your pet's experience as calm and comforting as possible. These vets prioritize your pet's emotional well-being from gentle handling and calming environments to using pheromone diffusers and anxiety-reducing medications when necessary. In an emergency situation, a fear-free approach can help keep your pet calm and cooperative, reducing the stress of an already difficult situation. Knowing that the vet will handle your pet with compassion and expertise when dealing with a stressful emergency adds another layer of reassurance. 3. Round-the-clock Availability Emergencies don’t follow a schedule. Whether it’s the middle of the night, a holiday, or a weekend, having an emergency vet in Orillia on speed dial means you have access to care 24/7. Many emergency clinics are equipped with advanced diagnostic tools and are staffed with experienced veterinarians who specialize in handling urgent cases. In addition to providing emergency services, these clinics are often prepared to perform necessary surgeries or administer specialized treatments that may not be available at a regular vet clinic. This means that your pet can receive comprehensive care without the need for a referral or a transfer, which could delay treatment. 4. Preventive Care Reduces Emergency Risks While having an emergency vet available is essential, practicing Preventive Care for your pet can help reduce the risk of many emergencies. Preventive care includes regular vet check-ups, vaccinations, dental care, and nutritional counselling—all of which contribute to your pet's long-term health and wellness. Preventive care can significantly decrease the likelihood of emergency visits by addressing potential health issues before they become serious. For example, regular dental cleanings can prevent infections that might lead to serious complications, and vaccinations protect your pet from potentially life-threatening diseases like rabies or parvovirus. A well-rounded preventive care routine allows your vet to monitor your pet’s overall health and detect any early signs of chronic conditions, such as heart disease or kidney problems. Early detection means treatment can begin before these issues escalate into emergencies. 5. Peace of Mind for Pet Owners Pet owners often experience a great deal of anxiety when it comes to their pets' health. Knowing that you have an emergency vet in Orillia on speed dial can give you peace of mind, especially if your pet is prone to health issues or has a history of accidents. It’s reassuring to know that you’re prepared for any situation, and you can rest easier knowing help is just a phone call away. In addition to emergencies, having access to an emergency vet can be invaluable when you're unsure whether a vet visit is needed. For instance, if your pet is showing mild symptoms but you’re concerned, you can call for advice and decide whether immediate care is necessary. This can save you from unnecessary trips while ensuring your pet’s health is always a priority.
