Can cats with white foam in their mouth recover without treatment?

First, we need to analyze the reasons why cats vomit white foam. If the cause is due to overeating or prolonged hunger, which leads to white foam in the mouth, adjusting the cat's diet and ensuring they receive balanced nutrients can help them recover. However, if the white foam is caused by poisoning or gastroenteritis, it cannot be self-healed and requires medical treatment with drugs.

Here are a few reasons why cats vomit white foam:

Indigestion or prolonged hunger. If the cat eats too much food at once, the vomit usually contains a large amount of food debris. In this case, temporarily stop feeding the cat and then give it a suitable amount of probiotics to help with digestion. If the cat is hungry for a long time, the vomit mainly contains stomach acid. Do not give the cat too much food at once, but provide it with small amounts of easily digestible food. As the cat gradually recovers, slowly increase its food intake and ensure it receives balanced nutrients.
Gastroenteritis. Cats have fragile gastrointestinal systems, making them susceptible to various causes of gastroenteritis, such as colds, parasite infections, stress caused by sudden changes in food or environment, and functional disorders of the gastrointestinal digestion microbiota. Cat owners can judge the cause of their cat's illness based on their usual care and management. If they are unsure or the cat's condition is severe, take the cat to the vet promptly to avoid delay in treatment.
Swallowing foreign objects or food poisoning. If a cat swallows objects like tissues or wool, it may vomit. It is recommended to take the cat to the hospital for X-rays to determine the type of foreign object and the degree of gastrointestinal damage, and then decide on whether to induce vomiting or perform surgery. If the cat accidentally eats toxic substances like rat poison, it is essential to seek medical treatment promptly for gastric washing.
Infectious diseases such as feline distemper. The feline distemper virus can damage the cat's gastrointestinal structure, causing vomiting, as well as diarrhea, loss of appetite, poor spirit, fever, and other symptoms. It is advised to seek immediate medical treatment.
