Good puzzle
My dog used to get puzzles often and loved them. We lost a lot of them in a house fire and subsequently move about a year ago and Im finally starting to replacing her old ones. She loves this thing. She definitely needs supervision because she’s already scratched it a bit from biting on it too hard but reasonably durable with that aside. (My dog is tough chew toys only kind of dog so fully expected) Easy to set up and fun for her is all I needed and it hit the mark

A fun puzzle for cats!
My 5 month kitten took to this puzzle right away as he watched me put food into each compartment. He solved it quickly and I think it will be a fun resource for his cognitive growth on a daily basis.

Great for mental stimulation.
Great for mental stimulation. Our little guy figures them out pretty quickly. He is very treat motivated. This one is excellent as sn activity to slow him down from gobbling his treats up so quickly.

I bought this for my Great Pyrenees puppy. I put chicken liver , beef cuts and chicken breast in every spot . I set it down went and washed my hands and by time I turned around he almost had everyone out already . It was entertaining for him and myself and kids . Worth the money

Best for small inquisitive dogs
This dog puzzle worked.for.abput a day until our lab decided it was easier to just chew on it until it gave up the treats. The outer ring of yellow sliders were good.but the red required interactive manipulation of the center sections that only frustrated our lab to the point where she just picked it up to chew and drop until it gave up the treats. Great idea, but not for a brute-force attack! I will say the plastic sliders have held up longer than expected but in the end our lab just had fun chewing it while carrying across the yard. She did enjoy it initially but I think grew bored or maybe frustrated with it. Probably best left to smaller breeds to fidget with.
