Q. Young kitten playing and seemed okay, then all of a sudden started crying and panicking, with foaming mouth. Will not eat or drink, but is purring

A. Foaming at the mouth in cats often indicates ingestion of something that was either not tasty or potentially toxic. Kittens are very prone to getting into or sampling things they shouldn't, so if your kitten appears to have signs of toxic ingestion (foaming at mouth, vomiting, diarrhea, lethargy or other symptoms), it is best to contact your local vet or ER clinic as soon as possible.
