It is very tempting to remove the cone but don't it's just too risky. I have been where you are and I know it's hard but just keep it on. Scratch him underneath the collar he will like that and it will probably make you feel better about keeping it on him. It's hard to watch him struggle with the cone but you have to do what is best for him in the long run. He can eat and sleep with it on and he will get used to it, just give it some time. So glad he's ok now. He is a big cutie!!!!
