Pro-Ject & Box Design
We have two indoor cats who are bonded brothers. They love to play with one another and snuggle together for naps, but one of them is a lot more energetic and playful than the other one. I've been looking for some good ideas for enrichment for him--he's VERY food motivated--but everything I've made/bought is either not very challenging for him, or it's too easily destroyed. Do you have any suggestions for good enrichment?
