"Pet Fit Club: U.K. Edition" -- it's not another ridiculously misguided reality TV program on VH1. It's actually a real contest being held by an English charity called the People's Dispensary for Sick Animals (PDSA).

The eight contestants, including seven jumbo dogs and one 22-pound cat, have grown from "cute and cuddly" to "experiment-gone-wrong-in-a-science-fiction-movie" ginormous.

To slim down, the chunk monsters will embark upon a 100-day program that includes diet food and exercise regimes specially designed for the animals, who weigh a combined 421 pounds. Hopefully pet-sized leg warmers and headbands will also be involved and maybe tiny roller skates and songs performed by Olivia Newton John. (When, oh when will they make an all-animal version of "Xanadu?!")

The PDSA is rewarding whichever pet loses the most weight and best follows its new health plan with the title of PDSA Pet Fit Club Champ, along with a pet-friendly vacation for the animal and its owner somewhere in Wales. Get it -- WALES ... animals ... whales? Oh, boy ... Hey! Look down there! It's our gallery of awesomely pudgy pets and corpulent creatures. Click through, and try not to gasp in "awwwww."
