Dear Befuddled,
Go slowly on the cat.

Even though he has expressed interest, it doesn't meet that he can deal with a cat right now. He already has a lot going on.

I love dogs, but if someone gave me a puppy/dog, I would have to give it back -- too much work for me. I can't have an extra creature in the house beyond hubby and me right now....too draining...not enough energy....

I know that your heart is in the right place.
Think of the kitty. It needs to go to a home where the person can deal with it and appreciate it.

Mari
