Paris Hilton has lost her pet puss after failing to pick up her cat from the vet. The socialite dropped Prada off to get neutered at the end of January, and when she failed to return for the pussy the vet called the woman Hilton adopted the cat from last year.

Now, catwoman Kris Kelly insists the hotel heiress has lost the feline because, as far as she's concerned, Hilton has abandoned it.

Kelly tells TMZ.com she even tried to contact Hilton in a bid to find out what happened - but the socialite hasn't returned her calls. Kelly says, "It's a clear-cut case of abandonment."
