Top Level Puzzle Challenger
My 2 puzzle hounds struggled to make quick work of this puzzle. They loved it and so did I. It entertained my 1 highly food motivated boy who pawed, scratched, and tried to gnaw his way thru to conquer. After 1 hr, and nearly completing all treat access he took a nearby rest. His other smarties brother began to finish it off. He was a gnawer and mouthed his way to pry off the sliding panel of 1 compartment. He only succeeded on 1 treat panel of the numerous panels offered. This would be 5/5 Stars if not for this. Ultimately I was able to force it back onto the slider tracks for continued and supervised mental and physical play. Still, it's the best puzzle challenge available.
