Super Pet Bounce Back Small Animal Toy Petsmart (in store, not online) - $3.99 RattyRat's Review: This is a treat dispenser in the form of a weeble wobble. This is a very durable toy, but poorly designed. It's impossible to find a proper treat to put in this toy that won't either poor out the holes or get stuck inside the toy making it impossible for your rats to get out. This is because the holes in this treat dispenser are all different sizes. We found this toy very difficult to use.
