I made a shelter for Sylvester, a stray cat in my neighborhood, and put it in the garage a couple weeks ago. I was thrilled to see him come out of the shelter for the first time this afternoon. So, he knows where he can go when it gets cold. Now it is dark ouside, and he came to say hello again. I don't think he wants to be a house cat, but I feel that he is becoming part of my family.
