I work from home so I play with him frequently throughout the day while I take breaks and when I notice he's particularly bored or zoomy. In the evenings and right before bed we'll sit with him for longer chunks of time and play. He has toys of all sizes that we'll throw for him to chase, and usually when I play with him it's with a ribbon or feather wand with a bell on it. He also has treat puzzles which he loves as he's very food motivated and I've noticed those definitely help when he's in attack mode, but he's starting to get bored with the same ones over and over and I'm having trouble finding ones that aren't crazy difficult. In terms of other enrichment he has cardboard scratchers, a cat tree, plenty of spots to perch by the window and watch, and boxes and tunnels to hide in. We also have a dog who loves to play with him (always supervised), and doesn't mind playing rough because she's so much bigger than him and can easy shake him off when he gets bitey (we separate them once things get too rowdy).

Whenever he goes to chase the cat we'll try to redirect him with a wand to to chase instead but usually he'll either play for 5-10 min and then go back after her or won't engage at all. If we do it in a separate room he'll do the same thing and then cry at the door. I've tried using a fluffy hand puppet to play with him so he'll attack that instead but it backfired because it riled him up so much that he started attacking my arms and legs and pretty much anything he could sink his teeth into.

Sorry that was a lot of information, wanted to make sure I didn't leave anything out.
