I once had a black and white cat that adopted us ( . . . after the Po-Leese raided a house a few doors down), came in, made himself right at home.
He was never led to climb in open cases, sleep on the amp, none of that warm and fuzzy stuff. But . . . . I used to practice REALLY LOUDLY, and he'd sleep on the couch not two feet away from the front of my raging 210/115 combination and never batted an eye. I could never tell what kind of music he liked either.
Cats. It's their world, and we're just living in it.
