Cotton has now taken up residence behind the crate. I can pet him with the cotton bat toy and even touch him with my hand IF I have the toy strategically placed to catch the teeth and claws!
I'm adding Calm Down to his food (now that he's eating again). Don't know if it helps him, but it would help me... it's 13% alcohol.
Yesterday, he seemed interested in what might be going on outside the bathroom door. I think he's just plotting his escape. I heard him banging on the shower door last night. I'm sure he'll figure out he's heavy enough to open it if he tries hard enough.
Mostly, he sits behind the crate and occasionally growls & hisses when I come in to talk to him.
