The one with a light on is the one I chose. I'm having to make some modifications to them but I hope to have them up tomorrow.
On a much sadder note, I think Kitty may have run away. We haven't seen him since yesterday afternoon. I did a little research this morning and learned that cats of his age are usually at their "maturity" level and may start seeking out female felines. If that's the case, his little body will be changing when he returns home.
