SallyC., for what it's worth I think you are doing the right thing. Not easy for you though. An adult cat might be the answer for you. They are pretty self sufficient and as mentioned a self cleaning litter box would be great.

I really wish our Humane Society would offer cats for not much money but they seem to want about $110.00 for them no matter if they are kittens or adults. Not in the picture for me.

Pal will have a good home as he's been there before as you said and so he knows them. Take care. And please leave the picture up. Sooooo cute.
