My cat hates resonator guitars. It's convenient, in a way. Any time he's being a pain in the ass, all I have to do is grab one and he's through the cat door.

Exactly how far away he runs depends on the specific guitar and playing style. If I play acoustic bottleneck on the round-neck, he stops at the front porch. If I play lap-style on the square-neck, he goes a bit further, into the yard. If I plug the round-neck into the Marshall and turn it up to "6", he hides in the woods until the next morning.
