Cat not right after boosters...

[longdiling]

Cat had her yearly boosters on Wednesday and hasn't eaten much since. She's been sneezing almost constantly since last night and has just crammed herself in a corner she wouldn't normally go in for a sleep. Are vaccines live? Could she just be under the weather because of the jabs?

They can be live. Or dead. Presumably.

Ours went off colour for a while. See how she is in a couple of days.

Cat vaccines tend to be live attenuated vaccines. Though actually usually the worst vaccination reactions come from the adjuvants.
I would only expect a vaccination reaction to last 24 hours so 5 days later I would suggest she is seen.
There is a non-adjuvanted vaccine on the market that has much, much lower rates of vaccine reactions that the other vaccines.

My boy gets like this after his jabs. Usually only a day or two though. I'd tempt kitty with all their favourite foods and give the vet a call if no change by tomorrow.

Thanks all. I'll definitely get her seen if no improvement.

Is she better, OP?
