My cat keeps vomiting undigested food. Why does she seem fine?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 11 years and 6 months old

My cat keeps being sick but I'm unsure why. She's fine in herself. Going you the toilet ok and has a healthy appetite. For several weeks now I have come home from work and she's been sick yet she'll eat in the evening and she's fine all night. I've changed her food and that helped for a week but now she's being sick again. It's generally undigested food. What could be wrong? Natalie

Hi Natalie! I'm sorry Gemma keeps getting sick. I see that she is a senior girl, and this vomiting could be due to diabetes, hyperthyroidism, kidney failure, cardiac disease, and cancer among other causes. I recommend having her seen by a vet for a physical exam, geriatric blood panel, urinalysis, and x-rays. These tests can help the vet identify if there are any medical illness causing her to vomit, and can discuss treatment options with you.

    Some causes for intermittent vomiting in a cat her age include a food allergy, IBD, issues with her liver/gallbladder or even intestinal cancer. With those conditions the normal blood tests can all be normal. She may need an ultrasound of her belly to see exactly what is causing her vomiting.
