My cat is losing weight. Is her current food causing the problem?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 1 year and 3 months old | 9.5 lbs

What are some ways of knowing if the food I feed my cat is not working for her? I've fed her Blue Buffalo since she was a kitten but lately she's been losing weight drastically. She has lost 2 pounds in the last 3 months and the vet doesn't think there's anything wrong with her.

This kind of dramatic weight loss is almost always due to an underlying medical condition. Ask your vet if he has checked Frida Katio's thyroid levels to rule out hyperthyroidism and performed full body X-rays to scan for any masses. He should also perform full mouth dental X-rays to rule out any dental disease that may be preventing her from eating. If all of these diseases have been ruled out, you could consider switching Frida to a higher calorie canned food such as Hills Science Diet AD.
