It's 4:20 AM here. The puppy had an operation yesterday and they put one of those cones on his head to stop him chewing his stitches, but as soon as he came round from the anaesthetic he started freaking out trying to get it off and I was worried he'd burst his stitches. So I took it off, and now I'm sitting up all night watching him sleep in case he wakes up and starts chewing. I desperately want to sleep but I daren't. Help.
