Why Is My Cat Foaming at the Mouth

Finding your cat foaming at the mouth is a startling sight. Of course, your mind will leap to the worst-case scenario. But before leaping into a panic, it's essential to know that cats foaming at the mouth can indicate various health issues, ranging from mild to severe.

There are six possible reasons why your cat may be foaming at the mouth:

Deepening the Understanding of Each Cause

  • Nausea: Just like humans, cats can experience nausea, often resulting from dietary indiscretions, infections, or even motion sickness. Nausea can lead to excessive drooling that results in foaming at the mouth.
  • Poisoning: Cats are curious by nature and may ingest toxic substances. Everyday household items like certain plants, human medications, and chemicals are hazardous to cats and can be the reason why your cat is foaming at the mouth.
  • Anxiety: Stress or anxiety in cats can manifest in various ways, including foaming at the mouth. This can be due to environmental changes, such as moving to a new home or introducing a new pet.
  • Seizures or epilepsy: While less common, seizures can cause cats to foam at the mouth. This could be a sign of an underlying neurological condition.
  • Dental problems or oral discomfort: Dental issues such as gingivitis, tooth abscesses, or oral injuries can cause pain and lead to drooling and foaming.
  • Rabies: Although rare, especially in vaccinated pets, rabies is a fatal viral infection that can cause foaming at the mouth.

Not sure what your cat’s been up to or if they’ve been behaving differently? A valuable tool for any pet parent wishing to monitor their pets for unusual behavior is the Petcube Cam. This handy gadget lets you observe your cat's behavior remotely, making it particularly useful for identifying unusual behaviors or symptoms.

  • Immediate observation: The Petcube Cam lets you monitor your cat in real-time, allowing for immediate observation and reaction if something seems amiss.
  • Recording behaviors: It can record videos, helping you track your cat’s behavior over time or share important footage with your veterinarian.
  • Peace of mind: The ability to check on your pet anytime provides peace of mind, especially when dealing with cats prone to health issues.

Cat Foaming at the Mouth After Medicine

One of the more common reasons for a cat to foam at the mouth is a reaction to medication. Certain medicines taste bitter or can cause a tingling sensation in the cat's mouth, leading to drooling or foaming. If you notice your cat foaming at the mouth after administering medicine, it's likely a reaction to the taste rather than a more severe health issue.

Other Symptoms Along with Cat Foaming at the Mouth

Foaming at the mouth can sometimes accompany other symptoms, indicating a more severe health concern. Is your cat foaming at the mouth but acting normally? It might be nothing serious. If you spot some of these symptoms, it might be time to get to a vet. Symptoms, including lethargy, loss of appetite, or vomiting, are particularly concerning. Monitoring your cat's behavior with a Petcube Cam can help track these symptoms and provide valuable information to your veterinarian.

What to Do When Your Cat Is Foaming at the Mouth

When you notice your cat is foaming at the mouth, the first and most important thing to do is stay calm. Take a minute to look for any additional symptoms. Assess the context of the situation – is your cat foaming at the mouth after taking medication? Has your cat eaten something that may be toxic?

If the foaming is isolated, without other symptoms, and stops after a short while, it may not be cause for concern and is more than likely a result of your cat eating something that didn't taste too good. If the foaming persists or is accompanied by other symptoms, you must contact your veterinarian immediately.

You should see a vet immediately if:

  • Your cat has been scratched or bitten by a stray dog or street cat.
  • Your cat has consumed something that you know to be toxic to cats, i.e., detergents, human medications, onions, garlic, or certain plants.
  • Your cat has collapsed, lost consciousness, or is trembling.

Preventive Measures and General Cat Care

Prevention, as they say, is better than cure. As a responsible pet parent, you should regularly take your darling cat to the vet for a routine general check-up. This will help you hedge any issues before they become more serious or difficult to treat.

Ensure your home is free from toxic plants, substances, and hazards that can harm your cat. Of course, we know that cats are mischievous little creatures, and accidents can still happen no matter how careful you are.

Keeping your cat in general good health starts with a good quality, nutritious diet and plenty of exercise. Overall, good health will keep your favorite feline healthy and happy and make fighting other ailments and illnesses easier.

Can foaming at the mouth be a sign of poisoning in cats?

Foaming at the mouth or excessive drooling can be a sign of poisoning, according to Vets Now research. Other symptoms that could indicate that your cat has been poisoned include heavy breathing, walking unsteadily, diarrhea, seizures, and vomiting.

If you suspect your cat has ingested a toxic substance, seek veterinary care immediately.

Should I monitor my cat after it stops foaming?

It's a good idea to watch your cat for any further symptoms or a recurrence of the foaming at the mouth.

How does the Petcube Cam help in these situations?

The Petcube Cam allows you to monitor your cat remotely, which can be invaluable in spotting early signs of distress or illness. Of course, you can't be with your cat all the time, so having a way to check in remotely is handy for keeping tabs on what your cat gets up to (or into) while you're out. It's also a great way to monitor your cat after an illness to ensure they're doing okay.

Do cats foam at the mouth when they are dying?

Foaming at the mouth indicates severe nausea, oral irritation, or discomfort. Both can be signs that your cat has ingested something toxic. If your cat was foaming at the mouth before it died, it’s possible that they ate a toxic substance, which led to death, or it could also be from a severe seizure.

Final Thoughts

Foaming at the mouth in cats can be alarming, but understanding the potential causes and knowing how to respond can make a significant difference. It’s always best to err on the side of caution in these matters and consult with a veterinarian any time you’re in doubt.

Having a Petcube Cam in your arsenal of pet parent goodies can support you in managing your cat’s health, ensuring that they stay happy and healthy for years to come.
