Cat sick, lethargic, not eating 10 days after vaccines. What to do?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed

My 7 yo female DSH got her rabies and feline distemper vaccines 10 days ago. She has poor appetite, very lethargic, and unlike herself. She’s warmer than usual also. She rarely even purrs. The vet asst gave both vaccines in the same place. Should I be concerned, and what can I do to help her feel better? Thank you.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Bandit! I don't think the fact that the vaccines were given at the same spot is why Bandit is sick. She definitely could be suffering from a vaccine reaction, which has nothing to do with where the vaccines were given. Since Bandit has been sick for 10 days I think it is very important to have her seen by your Vet. Cats can not go a long time with a poor appetite or they can become sicker (fatty liver). She may have a fever which is why she is lethargic and not eating well. If the Vet thinks she is having a vaccine reactions steroids are usually given as an infections and possible sent home as well. If the Vet feels something else is going on then they may do blood work or X-rays. I hope this helps and I wish Bandit a speedy recovery!
