My 9 year old female cat has been extremely lethargic for the past few days and her back legs seem slightly stiff, and she is walking with them further apart than usual. Usually she is very active, but now she only walks from one room to another and immediately lies down. She is acting kind of grumpy; sometimes growls when I pet her. She is hardly eating or drinking or using the litter box. Last night she laid down next to her food
bowl and I had to put the water bowl right under her nose for her to drink. She has never lied down to eat before!
Over two weeks ago, June 1, she had a FVRCP vaccine. I think she was fine right after that, but I've read terrible things about injection site cancers and worry about that. I've read online that the AAFP recommends the distemper vaccine be given only every 3 years and when we were in Massachusetts that's what our vet had scheduled. When we moved to Missouri, it was time for their vaccines -- it had been 3 years -- so they got them a year ago. Then the new vet gave them a vaccine just two weeks ago, so only 1 year after the last. Is this okay?
I also administered Frontline Plus flea treatment on her one week ago, but she didn't seem to have any reaction to it at the time.
By the way, my other male cat (age 10) who also had the vaccine and flea treatment, has been somewhat lethargic but not like the female. He is eating more and walking around; however, I have noticed he has been having trouble jumping up on the counter, which normally he does easily.
I called our new vet (the one that gave the vaccine) and they looked at her two days ago but couldn't find anything wrong. I dropped her off there, so I wasn't able to really talk to the vet in any length. I have another call into that vet, but thought I'd ask online as well.
I am worried because we plan to drive from Kansas City to Boston on Monday with the cats, and I don't want her to be in pain, or worse!
