That poor kitty! It's not bad enough that kitty is suffering such terrible pain, but this life form REFUSES to give the help poor kitty needs to be at leaset a little more comfortable! That's intentional abuse and neglect! Have you tried to take kitty back? This should definitely be reported and let the consequences be what they're going to be. This isn't a stuffed toy to toss in the closet, it's a living creature capable of feeling and right now she's feeling a lot of pain! Maybe the vet has some ideas.....
