My 4 year old male cat got his rabies vaccinations as well as deworming and Biofel PCH. Yesterday after he came back he was feeling ok, he ate and drank water and was able to walk nicely. Today he hasn't eaten much or drank water and only used the bathroom. He is also limping on his front legs and seems uncomfortable when moving. I know the side affects could be lethargy and lose of appetite but i am not sure about the limping. should i call the vet or wait until tomorrow.
