My 18 month old cat just had her rabies vaccine last night, and our vet didn't bother to warn us about any possible side effects afterwards. For the first few hours after, she was her usual hyper crazy self, and she ate her wet food dinner, but before I went to bed, she barely ate any of her late night dry food feeding (her favorite type of food). I woke up in the middle of the night, and normally when I do that, she comes running upstairs to me when I open my door, since she is always very active in the middle of the night, and she didn't do so. I went and found her on the couch in sleep mode and the area on her body where she got the shot was pretty warm (but the rest of her body felt normal temperature). Is this normal? She still refused any food this morning, and also went into hiding under my sisters bed and wouldn't come out (something she hasn't done since we first brought her home as a small kitten). Are delayed side effects such as these from rabies shots normal??
