Good for cats!
Makes my cat work for her food. She learned how to use it pretty quickly. I like being able to leave her a mid day snack in it and know she has to use her brain to get the snack from it. I have recommended it to a few co-workers as well.
ProsSolid product, good enrichment.
ConsTakes up a bit of room on top rack of dishwasher, is about the size of a dinner plate and the height of a phone book (If people know what phone books are anymore, lol) so not a tiny item to store.
