He is, at least, still interested in the soft food I give him his pills in, and he's licking the pan my dinner was in. He's at least able to get himself on and off the bed. Jim and Robin think he's got major arthritis issues, which is possible but still doesn't explain to me why he seemed to be so weak Thursday night and Friday morning he couldn't stand.
I'm watching him at this point, but I'm afraid he's about done with life. I don't want to ask him to hang on when he's ready to go, because I don't really think things are going to get better for him. Even if I could give him a magic pill that cured all his health problems, he's still 12.
Jim and Robin don't have any really helpful advice. They're not actually telling me to put him down, but they're making it pretty clear that they're supporting me in doing what I need to do, not trying to convince me that I'm overreacting.
