If your cat keeps throwing up white foam, this could be caused by…
If your cat is expecting food, their stomach will start preparing by releasing hydrochloric acid and gastric juices to digest the food.
However, if the food doesn’t arrive in the stomach, these acids and juices can cause irritation. To ease the irritation, your cat will vomit out these stomach fluids, which appear as white foam.
This usually happens if you’ve adjusted your cat’s feeding schedule, or when you’ve changed your cat’s diet and they reject the new food.
As they groom themselves, cats will swallow some of the fur from their coats. While most of it gets passed out with poop, the fur can sometimes accumulate in your kitty’s stomach and form hairballs, which are very irritating to your cat.
If this happens, your cat will vomit white foam as they try to expel the hairballs.
Gastritis is an inflammation of the stomach lining. This usually happens when your cat has ingested something they shouldn’t.
When this happens, your cat will vomit to expel the unwanted substance from their stomach, which could come out together with white, foamy liquid.
Inflammatory Bowel Disease
Inflammatory bowel disease (IBD) is another common reason why cats vomit white foam. This condition is usually accompanied by diarrhea. If your suspect IBD, you should take your cat to the vet immediately.
When Should I Worry About My Cat Vomiting?
You should take your cat to the vet for vomiting if the vomiting has been going on for more than 2 days, or if your cat is also showing other symptoms like lethargy, abdominal pain, loss of appetite, pain and distress, diarrhea, bloody stool, fever, or blood in vomit.
You should also take your cat to the vet if they’ve been previously diagnosed with another serious health condition.
