Hello! My cat just had foam coming from his mouth, but the amount was very small, and he seems totaly okay now. it was one time and it has not repeated. Should i worry? He is a house cat with no access to outside and is eating and drinking well, no unusual behaviour.

Thanks for using Petco Pet Education Center, formerly Petcoach! If the foam isn’t continuing and Vy is acting normal I wouldn’t worry. It is possible she licked something that didn’t taste good and the taste has now passed. If it continues, I would take her to a vet for a thorough oral exam. Good luck and kisses to Vy!

If it happened once and she seems fine than it probably isn't rabies. Rabies is a fatal disease and the signs get worse and not better. If you are concerned, have her examined by your vet to diagnose the problem.

While no vaccination is 100% effective, it is unlikely that what you are seeing is Rabies if the symptoms resolved. Once the foaming at the mouth has begun the symptoms of Rabies usually progress from there. If he is now acting normal, I would continue to monitor him for the time being. He may have come in contact with something orally that caused him to foam at the mouth. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further! If the symptoms persist, I would recommend having a veterinarian recheck him so that the most appropriate diagnostic and treatment recommendations can be made.

My dog threw up a little foam but seems fine. Should I worry?

This looks like a small amount of foamy vomit. If Precious is behaving normally otherwise I would just monitor. You can also offer a small meal of boiled chicken and sweet potato or rice to see if this helps to calm her stomach. If she continues to vomit or other signs of illness develop like diarrhea, inappetance, or lethargy I recommend taking her to your veterinarian. Hopefully Precious just has a mild upset stomach and it will pass quickly! Thanks for using Petco Pet Education Center, formerly Petcoach!

My cat is foaming at the mouth. What should I do if he ate medicine?

Poor Pye! Thank you for following up to state that he got some miconazole in his nose and mouth. This medication is only prescribed for topical use, and seems to only have minimal absorption if some is accidentally ingested. However, it can cause some stomach upset or even liver problems if enough is ingested. It's likely that Pye is foaming at the mouth because it tastes pretty terrible. I'm glad to hear that you've rinsed out his mouth! However, since I don't know how much he ingested, I'd recommend calling either the Pet Poison Helpline (855-764-7661) or the ASPCA Poison Control Center (888-426-4435) to discuss this problem with one of their veterinary toxicologists. Odds are good that this shouldn't cause any problems for Pye, but it's best to confirm with them the risk of causing liver problems based on how much of the miconazole that got into his mouth. I hope that all goes well!

My cat is licking lips and drooling with white foam. Should I worry?

Drooling, excessive salivation, and licking lips are all signs of nausea in pets. This may be the first signs of a gastrointestinal upset, she may have eaten something she shouldn't have. As this is the only sign Melodie is demonstrating, and is otherwise fine I would continue to monitor her. You could add a probiotic to her diet for gastrointestinal health benefits. http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=25718 Signs to be concerned of would be vomiting, diarrhea, lethargy and pain. IF you notice any of these please post another question so we can help you further or take Melodie to see her veterinarian.

My cat threw up white foam and has poop on her tail. Is she okay?

She may have just had a temporary upset stomach or a hairball. No worries. She will groom herself and get the vomit off. Just continue to monitor her for any decreased appetite, loose stool or lethargy. If she continues to vomit then it’s best to have her examined by your vet to make sure everything is ok. Best wishes and take care.

Why is my cat foaming at the mouth and drooling? Should I worry?

Nausea is a common cause of [drooling](https://www.petcoach.co/cat/condition/drooling/) or foaming at the mouth. There are several other causes as well, such as [dental disease](https://www.petcoach.co/cat/condition/dental-disease-1), oral trauma, tooth abscess, [stress](https://www.petcoach.co/article/10-signs-your-cat-is-stressed), tumors in the mouth, [stomatitis](https://www.petcoach.co/cat/condition/gingivitis-and-stomatitis), poisoning, and even rabies (rare if your cat is vaccinated for it). In the absence of other signs, such as [vomiting](https://www.petcoach.co/cat/condition/vomiting/), I would be concerned that this drooling and foaming at the mouth may be caused by a dental problem, such as a broken tooth or a tooth abscess. You should take Petunia into your vet for a health check and mouth exam. It would be a good idea to get her in a soon as possible (not an emergency, but first thing Monday) because if it is a dental problem, it will be very painful, and she will likely stop eating. Your vet can rule out other causes of these symptoms at the exam.

My cat threw up after acting strange. Seems better, should I worry?

Time will tell with this one. Since she's eating, drinking, and not lethargic, you certainly don't need to seek emergency care tonight. If tomorrow she still seems out of sorts, or continues to vomit, I would recommend scheduling a vet appointment for exam and x-rays of her abdomen. Good luck and thanks for using Petco Pet Education Center, formerly Petcoach!

My cat licked toilet cleaner. What signs mean she needs a vet?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! If the floor looked dry I am sure she is fine. I do not think she needs to see a vet. If you want to rinse her mouth out well with water as a precaution and wipe her paws well with water to prevent any more possible ingestion that isn't wrong. If she becomes lethargic, drools, won't eat or in anyway appears abnormal then bring her to the Vet. But based on your description I think she will be fine. Maybe have a discussion with your roommate about this so it won't happen again. I hope this helps!
