Thanks, half an hour later and he's perking up a bit, wanting to play. I'm mostly just ignoring him to avoid encouraging it while keeping an eye on him.
I was told not to offer food until breakfast tomorrow, and then only a small amount at first. I feel kind of bad about it, but I also don't want him throwing up. I'm hoping he settles down when I go to take my nap (long day, up early to drop him off, then off to get two teeth pulled for me
)
so we can all get some rest.
I'll move his litter box into the bedroom and shut the door when it's bedtime, though, that's a good idea.
