I bought this to address my cat's fast eating and have been using it for about two months. There are no noticeable scratches or stains. (Fully washed) It's so cute watching my cat work hard to spin it around, haha. ● A rotating drum-style food toy where food comes out when the cat successfully spins it. ● The drum, where the food is visible, is specially designed for cats with nimble paws. ● The size of the food holes in the rotating drum can be set to 6 different sizes, from 11 to 16mm. ● The rotating drum is designed to be difficult to detach but easy to attach, and is designed to be easily disassembled and washed. Made in Japan. ● A fun educational food toy that can be used as a slow feeder or a puzzle toy. The box is still kept, but please consider it as a bonus.
