Keyboard commands are fantastic bc it doesn't take much thought after a few battles.
I usually have a video on split-screen or have a podcast/livestream/etc playing in the background. I also make myself get up to take breaks to stretch and such halfway thru the adventure, or at every major checkpoint.
Heck, sometimes i play with my IRL cat while passively grinding thru fights
Adventuring also helps me come up with lore/headcanons for some of my cats, and I'll take breaks to add to their bios, dress them differently, or adjust my scenes.
