Reward your cat for exercising! The Egg-Cersizer treat-dispensing toy can be used to make playtime more fun or help your cat lose weight. Fill it with treats or your catís entire meal. Open 1, 2, or 3 of the dispensing holes to customize how fast the treats or dry food come out. Decrease the number of openings to increase the challenge over time. Itís a great way to slow down cats who eat too fast and encourage your cat to work for each meal.
