On Friday, my cat had her annual rabies and FCRP-FELV vaccines. Included was a steroid in the shot because Kay had a re-action last year, fever and lethargic feeling. She goes outside so needs these vaccines. It is now Saturday evening and she still is lethargic, doing not much else other than sleeping. Is there anything I can do for her, or just wait it out. She did not vomit, go into convulsions or anything like that, but she is not eating and has drank only a very little amount of water since Friday morning, breakfast. Any thoughts would be appreciated.
