My cat has flu, is on antibiotics, and won't eat. What should I do?

Updated On September 23rd, 2025

Hello, My cat has been diagnosed with cat flu and was given antibiotics 2 days ago. Since giving him antibiotics, his voice has become hoarse and has refused to eat anything but is still drinking water. I’m really concerned and do not know what to do.

It's very concerning that your cat is refusing to eat. When cats don't eat, they develop a fatty liver that is fatal without treatment. It could be he's really congested and can't smell his food, leading him to not eat. Try gently warming really smelly wet food such as sardine or fish based to see if he will eat. If he does not eat that, take him back into the vet today. Best of luck.
