I got my very first kitten home the day before yesterday, when she arrived she was completely vaccinated against cat plague and feline cold. She’s about 13 weeks old.
When she came home she was snotty and of course terrified but then the next day we cuddled a lot but she is warm and snotty and generally sluggish just slept all day and I wonder if I should be worried?
Yes, it’s unfortunately something to be a little worried about.
Most cats do not react at all to the vaccine but there are those who can get a reaction.
Does she eat and drink?
If not, a veterinarian should be consulted promptly.
If she eats and drinks as usual, you can wait a while, but if several days go by without her becoming more alert or if she gets tired or stops eating / drinking, a veterinarian should be consulted immediately.
Hope everything goes well with your cat!
