  • When the owner sees white foam coming from cat’s mouth, which occurs once, then it is not worth panicking about it. It indicates that the stomach of the animal is empty at the moment. That is, the food is passed into the intestines, and there is gastric juice left in the stomach, which irritates the mucous membrane of the stomach. This results in the secretion of mucus, which is mixed with air and gastric juice, and turns into the form.
  • A pregnant cat may release the yellowish foam, which might be mixed with food. Usually it disappears after eating or sleeping.
  • There are cases when increased salivation caused by nervous shock of pet can cause foaming in the corners of the mouth.

    My cat just threw up 3 times and ran out with foam in her mouth making a sucking sound. This has never happened before. I tried to wipe off her face and open her mouth to see if something was stuck but she wouldn’t let me open her mouth. I don’t know what else to do except call the vet in the morning.
