There are three kitties that visit my house- ace, duo and thrice. Ace is a little nutty- he/she comes most often, and is a white kitty with tabby spots. Duo was originally the one which came less often, and looked larger than ace – also white and gray but her spots are solid. Thrice is an Orange marmalade kitty I have only seen once.
Duo has taken to sitting on my porch all night, only leaving when I peer at her directly through that glass, although she sits directly across from my chair so I can see her through the window as I’m quietly sitting.
