Why Do Cats Drool? Cats may drool for several reasons, ranging from happiness to underlying health issues, so it’s important to understand why your cat might be drooling to ensure their well-being.
While some drooling can be normal, especially when your cat is relaxed and purring, excessive drooling could indicate a more serious problem that requires attention.
Common Reasons Why Cats Drool
- Contentment and Relaxation: One of the most common and harmless reasons for a cat to drool is when they are completely relaxed and content. Some cats drool while being petted or when they’re purring, much like some people drool in their sleep. This type of drooling is usually minimal and not a cause for concern.
- Nausea: Cats might drool if they are feeling nauseous. This can happen if they’ve eaten something that doesn’t agree with them or if they’re dealing with motion sickness during travel. If your cat’s drooling is accompanied by vomiting, it’s a sign that you should monitor their health more closely.
- Dental Issues: Dental problems are a leading cause of drooling in cats. Conditions such as gingivitis, periodontal disease, or tooth abscesses can cause significant pain and drooling. If your cat is drooling excessively, especially if it’s paired with bad breath or difficulty eating, a visit to the vet is recommended to check for oral health issues.
- Foreign Objects: If a cat has something stuck in their mouth, such as a piece of string or a small object, it can cause drooling. This is a situation that requires immediate attention as the object could potentially cause choking or other complications.
- Poisoning or Toxic Substances: Exposure to toxic substances can also cause cats to drool. This includes ingestion of household plants, chemicals, or certain human foods that are harmful to cats. If you suspect your cat has ingested something toxic, contact your vet immediately.
- Respiratory Infections: Upper respiratory infections in cats, similar to colds in humans, can lead to drooling. Cats may have difficulty swallowing due to the mucus buildup or throat irritation caused by the infection. If your cat is also sneezing or has discharge from their eyes or nose, it’s likely they’re suffering from a respiratory issue that requires veterinary care.
- Stress or Anxiety: Stress and anxiety can cause a cat to drool. If your cat is in a new environment, traveling, or experiencing a stressful situation, you might notice some drooling. This should subside once they’re calm again, but if stress is a frequent trigger, it might be helpful to explore ways to reduce anxiety in your cat.
