The Twitterverse went nuts last week when The New York Times tweeted "Fat cats don't hold a grudge if you put them on a diet, a new study shows." Indeed, it's true. Veterinarians at the Cornell University College of Veterinary Medicine took 58 obese cats, randomized them to three different diets for 8 weeks, and asked their owners to record their behavior over that time. They found that the cats were actually more affectionate after their calories were restricted. Even better, more than 75% of them lost weight, according to the study, published in the Journal of Veterinary Behavior. Overall, the cats on a high-fiber diet did the best, losing a median of 6.5% of their original weight. The study's lead author told the Times she believes cat owners inadvertently create fat cats by rewarding affection with high-calorie treats--a behavior on the part of pet owners that may not be necessary, according to this trial anyway.
