Pros: Well made, easy to clean - my cats love it
Cons: need to check for nails inside
I've had one of these for about 4 years, along with a Seek-A-Treat Shuffle Bone Dog Puzzle. My cat's love both of them. Especially Lucy. Several times throughout the day, she finds me and leads me to the puzzles. I use them to dispense treats. I drop a piece of freeze dried shrimp or chicken inside, sit back and watch the fun. Each of my cats uses a different technique to retrieve the food. Overtime though, Archie, my tabby, figured out that he could let Lucy do all of the work, then swoop in and steal the treat - naughty boy.
The puzzle box can also be used for toys. Though, my cats quickly grew bored fetching balls and toy mice. As a treat dispenser and mental stimulus, the product works great.
The Peek-a-Prize Prior is well constructed and looks nice. However, prior to purchase I read that some users reported nails sticking out inside the box. Mine had that issue. I'm so glad I checked mine; it could have caused serious injury.
