That's awful. Just, completely awful. I even know how you feel with the "I'm NOT giving my cat up, but there comes a point where I just can't AFFORD it." I had to give up Chico to my mom because I simply could not afford to keep up with his medical bills--and I got lucky that I had someone like my mom to take him back as a housecat who can spend the $100 every three months to keep him alive and comfortable. But, it's got to be the absolute worst part of this whole thing is watching Grim in pain, knowing that you WOULD help...if you could.

I hope for a stroke of good luck to come your way, in one form or another: either Grim gets better and stays better, or you get a sudden windfall of cashy money.

Stay strong for the kitty. There's still a good chance he'll pull through this okay.
