Absolutely, speculating right now is all anyone can do. When we can get him to the vet I don't know if I'll be able to do xrays, if it isn't able to resolve itself I'm likely going to have to have him PTS. I'm hoping for the best, though. He moves normally so nothing appears to be broken, and I'm fairly confident that his chest was not hit, knowing his behaviour, and in the 15 seconds it takes to open the door, sit down, and close the door, he would only be poking his head out sniffing and looking out.
