Review on Interactive Cat Treat Puzzle - Nina Ottosson By Petstages Buggin' Out Puzzle & Play: Boost Your Cat'S Playtime And Intelligence by David Sidman

This toy was a big success with my cat. It's lightweight and easy to throw, the feather enhances attraction, and the woven fabric makes it easy for the cat to catch and hold. The opening for the treats is just right to let one or two out at a time, and the clear window makes it easy to see when it needs to be refilled.The downsides are that the fabric doesn't hold up to claws for more than a few days, and sometimes it slips and covers the hole a bit so that the treats don't fall out. If these issues could be resolved, it would be a perfect toy. Still pretty reasonable for the price at the time I purchased.
