Very entertaining
It's a good toy to keep your kitty entertained for a while as they figure out how to get the treats out. Plus, you don't have to worry: there are no pieces that could come loose and be swallowed by the cat. The only 'but' isn't the toy's fault: my cat has no patience, she's spoiled, and if she has to work too hard to get the treat, she just gives up. But it works, and I'm sure it stimulates feline intelligence.
