Small Animal Round Treat Basket www.petco.com - $4.49 Product Description: Our Treat Basketl is the ideal size to fill with fresh vegetables, hay or your pet's favorite meals. Easily clips to any wire cage. Includes a bell for added entertainment. RattyRat's Review: This is a wire ball with a chain that you can hang in your rats' cage. You can usually find this item in the small pet section at Petco or Petsmart. You can use it just like the Toyshoppe Playables wire ball, although this ball is bigger. Take some treats and wrap them up in some plain white paper towels and shove them into the wire ball and hang it in the cage. Your rats will have lots of fun trying to get the treats out!
