My 4 year old cat had a 3 year rabies shot and a distemper shot at about 11:30AM this morning. It is now 9:25 PM and she is having tremors in her leg muscles. It is NOT a seizure but I’ve never seen muscle tremors like this before. She is also lethargic and not eating too, which I know is fairly normal…I’m just worried about her muscle tremors. Does she need to be seen immediately or is it ok to wait until morning to call the vet?
