Welcome to The Cat Site.
I don't think the consequences are great--but I'd question the vet why he chose the spot s/he did.
I believe you may be thinking about this. Interestingly, the picture accompanying the articles shows the shot being administered in the cat's nape. And this.
The theory behind the placement of injections is: how easy is it to get to should cancer develop.
As both links indicate, vaccine associate sarcoma is extremely rare--and the consequences of not vaccinating your cat may be far greater than vaccinating your cat.
A lot has to do with your individual cat, including whether she/he is an indoor cat. And the advice of your vet and your own comfort level.
Ritz is a strictly indoor cat and seems to have a flare up of her FHS symptoms when vaccinated (rabies and distemper). So I have elected not to have her vaccinated against rabies and will be in discussions with my vet about subsequent distemper vaccinations.
thank you for the info you posted. it made me fell better. it wasnt a vet that gave the vaccine it was a breeders helper which when she gave it I cringed. thank you again!
Yeah, I'd cringe too. I hope the breeder's helper was qualified to give shots--don't know the law where you [or I] live.
Did you get the proper/legal paperwork showing your cat had been lawfully vaccinated? With the lot number, specific type, brand name, expiration date? You'll need it if animal control ever comes knocking on your door asking for proof of rabies vaccination, or if you ever have to board your cat or if your cat was bitten (by any animal).
