The next door neighbor's cat that I talked about in my last post is definitely an inside cat, most of the time. but, they take him out for little "excursions" every now and then. Errrr!
We rescued a kitty off the street, too. It took a couple of (winter) months before she figured out that its warm inside and there's always food. It wasn't too hard to keep her inside because there's only Bob and I, no kids running in and out. Otherwise, it would have been very hard!
