Shelter Cat

I adopted my cat Shadow from the Dumb Friends League a week ago.  The first few days he was acting very outgoing and friendly.  I took him for his free vet check up four days ago where he received the Feline Leukemia shot.  That evening, he started sneezing and acting uncomfortable.  He has not been himself for the past 4 days and hasn't been very social.  Do you think he has an upper respiratory disease?   Or a bad reaction to the vaccine?

Could be an URI, have you rang the vet to see if it could be an adverse reaction to the vaccine? 

I would definitely discuss his change in behavior with the Vet.  Could be a URI, or could be an issue with the vaccine. (a reaction)

Is he still eating, drinking, peeing, pooping like normal?  That is of major concern or it becomes an emergency. 

Oh, BTW, congrats on your new kitty .  Hoping he's back to feeling good in no time.

He is back to normal!  He did have an URI.  Very glad I took him in.

It was a URI!  He is all better.
