Nothing, not going to ask again. Last time it was $300 in tests just to say "Yup, he's old"
There's only so much they can do, and we aren't willing to spend a ton of money at this point just to keep him alive. Really it's for us not for him and that's selfish. If it is his time, I think we should let him die happy IMO.
Going to give him some hugs and cheese and steak and let him enjoy his remaining time.
