A man's dog has a problem so he takes him to the vet's.

The vet looks at the dog and says that he'll have to take him to the examining room.

In the examining room, he takes a cat out of a cage and lets the cat walk all over the dog, but the dog doesn't do anything.

The doctor say "Your dog is dead."

The man goes out to the receptionist and asks for his bill.

"That'll be $325" says the receptionist.

"What! $325? How's that possible?"

"It's $25 for the consultation, and $300 for the Cat scan."
