Hold on... don't put him down yet. Mine jumped out when he was about 16", landed 5' below on hard tile and sat there in the middle of the night for quite a while until the dog woke me up. He was almost dry and barely breathing when I put him back in. He did the headstand for about 1-2 days and then slowly came out of it. It was about 3 weeks before he ate again, but he survived. Just let him be.
