My cats are slugs. I buy "cat enrichment" toys so they don't become one with the furniture. Some work, some do not.
They have been at this for 2 straight days. Super simple, really clever.
We have crinkle tunnels, laser pointer things that rotate around the room and work on a randomized timer, trees, posts and yes, just plain boxes (they get to play until recycling day).
This, though - it's a puzzle and a box and treats. Like a trifecta of cat happiness. 😺
We shall see over the long haul, but so far all three are digging it - which is also rare.
