Up to 2 out of 3 cats weigh too much. This puts them at risk for diseases like diabetes, can make it hard for them to move, and may shorten their lives. Diets can work but are often hard to stick to. A new drug, like new weight loss drugs you may have heard about for people, has been developed for cats. 

 If enrolled, your cat will receive ten weekly shots under the skin of either the new drug or a placebo (saline). Neither you nor the researcher will know which shot your cat is getting.
