Hi Snow!

Long time no see. Fancy meeting you here

never ever vaccine sick cat.. i think the vet won't do that aswell.. im pretty sure your kitten has high temperature which makes him sick. so he dont have appetite to eat. most vet will give antibiotic.

if your cat has diarrhea, he/she can't even get vaccine.. need to be in perfect condition if u want to vaccine them.

u mention gravy and chicken wing = if this is human food, please avoid... im pretty sure our food gravy contain alot of onion, ginger, etc.. which is not a good food for cats.

oh i thought like BBQ chicken wings lol.. if it is half boil chicken wings why not... it has lots of protein anyway.

now im confuse, has u vaccine the kitten anyway? if yesterday you vaccine him, for sure lah today will feel sick abit. that's the reaction of vaccine.

but if u havent vaccine yet, then, hmmm feeling weird too.. most cat that do not want to eat is because of fever. some suffer for teeth/ulser/mouth problem which makes them feel hurt when eating.

yeap if he change appetite after vaccine that is normal. they will be moody, sleeping... thats the reaction of vaccine..

if this continue for more than 48 hours call your vet. you vet didnt tell you about this is it? my vet always remind me to bring my kitten if she looks weird for more than 48 hours. because some kitten cannot tahan with the side effect of vaccine. some even died.

but if it is not 24 hours yet, no need worry lah, thats normal for all kitten after vaccine. 

p/s when they are hungry sure will eat let them play till tired, sure hungry later eheheh
