PetSafe's SlimCat distributes an adjustable amount of dry food as the cat plays with it. By providing smaller portions of food throughout the day, it helps maintain optimum weight and improves your cat's digestion. SlimCat can be used by all cats and particularly overweight cats can benefit from the interaction. Fill with a healthy portion of dry food and watch your cat shape up. Made from BPA-free plastic, it holds up to 2/3 cup of dry food or treats and is dishwasher safe. With around 50% of the cat population showing signs of obesity, SlimCat is a fun solution to this "growing" problem.
