I came back for something...now what was it?

I got my kitty back. Well, he's not MY kitty. I'm fostering him. He had stopped eating for a few days (he's pretty skinny to begin with) and I took him to the Vet. He was there for about a week. The doc couldn't figure out what is wrong with him other than the fact that he is anorexic and one of his kidneys could (and probably is) failing. Well, i guess that Maximum decided that he likes the expensive canned cat food. He has developed a taste for Fancy Feast GOURMET with shrimp and tuna. Seriously, why cant he just be normal and eat regular cat food. Oh well, as long as he is eating i'll feed him what ever he wants.
