After reading your comment, I did some research, and it would appear you're right. This kitty is apparently part Maine Coon, or at least some long-haired variety of cat. It has a tail as big around as my arm. So I couldn't even tell if it WAS a male or not. Maybe that's the reason for the eartip.

Judging from the battle scars, I was just assuming male, but who knows. Wow, thank you so much. I feel a lot better now, at least knowing it won't be getting pregnant (or impregnating any other kitties.)
