I know that other cat is around here somewhere. The other day he was right outside the door and BigKitty opened the door a little and we growled at each other some. I haven't seen him since then but I can smell him sometimes. Yesterday I was on the porch and I thought I heard him. I ran over to the side of the porch but I didn't see anything. But I know he's there. It makes my tail puffy just thinking about it.
