How many shots did chloe get?
I only let them do one innoculation per visit, per cat.

I find that 'overloading' with shots makes it harder to determine which shot is causing the problem.
I know that my Mr. Jones has a problem with shots. I expect him to go into a 'deep funk' for 24 hrs.

When Snowy was a little kitten he got his, and he ended up shaking. Dr. told us to give Johnson's baby aspirin. I guess he had a fever.

Oh, and one other thing. Many of the shots that vets recommend are truely unneccessary. The only absolute 'gotta have them' is rabies (as required by law) and distemper. All others are on a case by case situation.
Does your cat go outside? (contact untested cats) Then yes to FeLV/ FIV.
It causes some site carcomas, so should be given low on the (same) leg, not on the shoulders. (a cat can live without a leg, but can't live without shoulders)

FIP vaccine? No. Poor effectivity rate, as most cats already carry the anitgen, along with as many as 20 other corona virii. Test for FIP? No.

If you want more info, PM me.

I'm glad Chloe is getting over her 'funk'.

Kiss those 'oreo' toes for me.
