Reasons Your Pet Might Be Foaming at the Mouth

As a pet owner, you’ve undoubtedly heard of rabies, and the moment you discover your cat frothing at the mouth, your first thought is that your beloved pet has turned rabid.

While this is certainly a possibility, especially if your pet has been exposed to other animals, rabies is an unlikely scenario if your cat has been vaccinated.

Since mouth-foaming doesn’t occur until the late stages of rabies, your cat would’ve been rabid for some time before developing this symptom.

Rabies also causes behavioral changes, aggression, and drooling, so you should monitor your cat for other symptoms.

Unfortunately, there are no available rabies treatments aside from booster shots, so most likely, your cat will need to be euthanized.


Just like us humans, cats tend to feel nauseated. This can cause cat foaming at the mouth. Cats can feel nauseous when pregnant, diabetic, suffering from gastritis, or experiencing motion sickness. Apart from foaming at the mouth, symptoms of nausea may include fatigue, loss of appetite, and lethargy.


Your dog will pant if they are working or playing intensely. The saliva in its mouth might bubble up due to its panting. The foaming should stop as soon as it consumes water and calms down. This is one of the most prevalent foam causes in pets’ mouths.


Seizures in dogs may cause them to froth at the mouth. It may be visible, with a dog collapsing and jerking its legs. Other times, the signs and symptoms are milder, such as mouth foaming. If you fear your dog or cat is having a seizure, please contact our office right away for assistance.
