Well, when we let him out regularly, he'd follow us to the mailbox and back, darting a head to search out, then come back. He begs for attention like a dog. Wags his tail. Jumps like a dog. Rolls over onto his back for belly rubs.

The only thing he does like a cat is bat my head with his own.

The wall thing must be inherent, mine did that too, for a while. Now, he runs into screen doors and bounces off.
