Mary, if the black cat came to your front door, then I'd say she was looking for something to eat, or is looking for a new home. The new next door neighbors to me brought a tabby with them. She was in my driveway the other day. I did not know if it was a stray or belonged to someone in the neighborhood. I tried to coax her out from a stack of lumber. But she did not know me and did not come out, yet it did meow when ever I said anything to her, as if talking. However, if the cat is a stray, perhaps you could build a box for her and keep food ready.

I know what it is to move into a new residence. Did all go well, and how did your 7 furkids take to moving?
