The Slim Cat Toy Ball Feeder is an entertaining way for your overweight feline to lose weight. SlimCat is a transparent, pink ball you fill with your cat's favorite dry food. As your cat plays with the SlimCat ball throughout the day, a premeasured serving of food is dispensed. The smaller portions of food help with your cat's digestion. Interacting daily with the SlimCat helps increase your pet's activity level as well as his or her awareness. The SlimCat assists in decreasing problem behaviors such as excessive meowing, attention seeking, and scratching by keeping your pet occupied for hours. The SlimCat is FDA approved and dishwasher safe.
