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.
