Why is my cat walking funny and swaying after taking antibiotics?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered

So I recently took my 1 year old cat to the vet and they put him on antibiotics for an upper resp. infection. A few days ago he started walking funny. When he does try to walk his hind legs sway and makes it seem like he is going to fall over. I have no idea what is wrong with him.

I'm not sure what is causing it either, it's probably not related to the upper respiratory infection or to the treatment though. you will need to take him back to the vet so he can be physically checked for this new condition.
