Common Causes of White Foam Vomiting in Cats

Empty Stomach and Acid Build-up

One of the most frequent reasons cats throw up white foam is an empty stomach. When cats go too long without eating, excess stomach acid and bile can accumulate, leading to irritation and vomiting. This often occurs in the early morning hours, especially if your cat hasn't eaten since the previous evening.

Hairballs and Grooming Habits

Regular grooming can lead to hairball formation, which may cause your cat to vomit white foam before or during hairball expulsion. Long-haired cats are particularly susceptible to this issue, making regular brushing essential for prevention.
