Biscuit, a 37-pound cat, looks at his cage in the shelter in St. Charles, Mo., in this Wednesday, Feb. 27, 2013 image made from video provided by the St. Charles Animal Control shelter. At more than two-and-a-half times the size of a normal cat, the shelter says the the morbidly obese feline has been put on a diet, but he needs an owner who will closely monitor what he eats.
