Meet Tinks. That's not just Tink's fur that makes him look poofy. Tink weighs over 25 pounds.

Apparently, Tink gained all that weight by cruising the town as a stray and mooching several meals a day from an assortment of kindly neighbors. Now all the poor cat can do is sleep, since he can barely move.

Enter "Pet Fit Club," an effort put together by the UK's PDSA charity. Several program members, Tinks included, are trying to shed a grand total of more than 165 pounds in a competition to see who is the feline world's Biggest Loser.

I'm sure the fitness club endorsements are going to come rolling in any time now. With a Richard Simmons show to follow.
