Thank you, Uabassoon, for understanding that I don't want to test Alfie at this point in his life. It wouldn't be fair to another cat, for one thing, if Alfie hissed or got mad at it. I've just started looking for a home so I'm sticking with him being #1. I know that will eliminate nice offers but I don't want nice people to waste their time and good intentions. I could be wrong and am not totally closed-minded because you all know so much more about cats than I do. I'm really basing it on his hissing at cats outside where he lived in a trailer on the beach. Or, at my 2 dogs inside the trailer but he tolerated them. This was normal, I'm sure. So,
if the right situation came along, another cat might be good as a companion. Thank you all for your interest in this saga.
