First, I just called my vet but as I'm waiting for someone to call me back I thought I would ask here and possibly get some opinions in the meantime. I took 2 of my cats in for a checkup yesterday to get vaccines and to get tested for PKD (a cat related to them had PKD and HCM and recently died, but these cats have absolutely no symptoms - I'm just checking them to make sure). So the appointment consisted of a full blood panel, a urinalysis, and 3 vaccinations (FVRCP, rabies and FeLv). I have 10 cats and have never seen one have any negative reaction to a vaccine, including the one I am worried about right now. Oreo has been pretty lethargic since late yesterday afternoon. He's alert, but he's sleeping more than usual and wasn't interested in food last night or this morning, though when I brought a treat right to him he gobbled it up instantly. He's purring (he is ALWAYS purring, and based on my other cats, when the purring stops, something is usually wrong) and like I said, he seems alert, but just....off. I've been reading up on vaccine reactions and this seems to be a typical reaction. But everything I read says something differently. Some things say to call a vet if this persists for more than 24 hours. Others say 1-3 days, and a few things I have read say 1-3 weeks. His symptoms seem to be symptoms most associated with the FVRCP vaccine.
So on one hand, I'm not too concerned because it does seem to be a "normal" reaction. On the other hand, I've never seen this happen before so I don't know if I should be worried or not. Oreo has been vaccinated before and this didn't happen ever before, at least not that I can remember, and I think I would remember this! I called the vet, but I guess I'm wondering, should I panic and rush him back to the vet? Give it a few more hours? A few more days? Has anyone had a cat with any negative reactions to a vaccine before?
