He just turned a year, found the hole just a few mins ago. Moved a desk in front of it to keep him from chewing more. Is there something in the wall he is going after? I am wondering where the pieces of drywall are - none to be found, did he eat them? He removed some paint and a like a few months ago in this same room.
He was a feral kitten 3 - 4 weeks old when I got him, handfed him etc.
