Sometimes when I open my old home window I found some dead rats and I found her too, I don't know her name but I always put some food out of my door for her when she visit us, luckily she argue only with my oldest female cat but she is OK with the little ones they look like friends, that's so lovely.
She is really cute and she love cuddles, I'm always happy when she visit us, she love to enter in the house too, I know she have a owner, probably one of our neighbors, and probably my cats visit him too.
She look very calm and quite. She is ajways welcome at our place.
