Why is my new kitten still foaming at the mouth after seeing a vet?
Updated On September 23rd, 2025
Very concerned about my new kitten who started foaming at the mouth on his 2nd day home. I took him to the emergency vet today where he was given fluids & anti-nausea meds. They did blood work & an X-ray but couldn’t define a cause. I’m home with him now and watching him closely ... he’s been sleeping with intermittent periods where he wakes briefly and, as soon as he does, the frothing starts again. I have no idea what it could be. Next plan is to take him to another hospital for 2nd opinion

Poor kitten! Excessive drooling like that can definitely be caused by nausea, as well as irritation of the mouth, throat, nose, or stomach. Getting into something potentially toxic or bad tasting, flea and tick treatments for dogs accidentally used on cats, or underlying illness can also cause foaming like this. I would definitely take him to another vet ASAP since it is so severe.
