The Question
“Dear Dr. Paola,
My cat, Mirabella, threw up more white foam. One of the posts on Catster shared what to look out for in different cat vomit, so I’m very concerned. I have spoken to the vet office that I take my cat to, but I’m still stressed. Can you help? – Catherine
Quick Info about Mirabella
Hi Catherine,
I completely understand why you’re feeling stressed—seeing Mirabella vomit, especially white foam, can be unsettling. Vomiting in cats can have many causes, ranging from mild to serious. White foam often suggests that the stomach is empty, which can happen if a cat goes too long without eating, has mild gastritis (stomach irritation), or is experiencing an underlying issue like acid reflux. However, frequent vomiting, lethargy, decreased appetite, or any other changes in behavior could indicate a more concerning condition, such as an obstruction, pancreatitis, or an underlying illness.
Since you’ve already reached out to your vet, that’s an excellent step. If Mirabella continues to vomit, seems uncomfortable, refuses food, or develops any other concerning signs, she should be seen promptly. In the meantime, offering small, bland meals like plain boiled chicken or a sensitive stomach diet in tiny amounts may help settle her stomach. Keeping her hydrated and monitoring for any changes are important. I know this is stressful, but you’re doing the right thing by being attentive. If her vomiting persists or worsens, following up with your vet for a more thorough evaluation would be best. Mirabella is lucky to have you looking out for her!
I hope she gets better soon,
Dr. Paola
