Ended up just gathering dust. Sharp edges. Takes up a lot of space, falls over.
Only 1 of our 3 cats showed an interest, and that was short lived! She would scoop the treats towards her and over the edge, unless they got stuck in a groove.
The top 'lid' didn't really fit adequately, and the plastic edges around the holes where cats push their paws through are rather sharp and scratchy. It's big and cumbersome and the dog knocked it over all the time.
If you have a cat that loves it, and uses it a lot, cleaning it is will be awkward with the scratchy edges.
