Paris Hilton has lost custody of her pet pussycat after failing to retrieve the feline following a trip to the vet. The socialite dropped Prada off to get neutered at the end of January and never came back.

The vet called Kris Kelly, the woman who Paris Hilton adopted the cat back in 2007.

Kelly tells TMZ.com that she tried to contact Paris in a bid to find out what happened – but the socialite hasn’t returned any of her calls. Kelly says: “It’s a clear-cut case of abandonment.”
