well I am tearing up and tearing- your loss reminds me of mine with a baby I had years ago. the vets dx with fip, no spinal fluid when a tap was done but I would not euthanize him. I brought him home and having dragged the futon into the kitchen where the source of heat was from an old stove (truly!), lay there with him for 2 days while he was in a coma. Turned him over often, changing towels as urine just came out of him. Cheops was his name. He was only a kitten, like your boy. I hope they now know each other and are romping over the RB! They know we love them! How can they not! I know it doesn't seem possible now, but what gave me the motivation to keep going was knowing I would see him again one day- it was all I could think of or I thought I would die crying! (By the way, I called in late to work the day I did decide to let the vet let him go, my supervisor was Cruel! Said I had a "problem", "For God's sake Leslie, it's a CAT, I think you should deal with your problem, I expect you hear no later than....!" (Bitch). That felt good. I don't think I've talked about that in years.....
