Our 2 1/2 year old brother and sister pair. Charlie and Bella. I still trying to figure out if their Chatreux, Russian Blue, British Shorthair or a mix of all.
He is totally a stud. Indoor cat with no front claws, got out in a cooold January 13 years ago and was gone for a month. Hasn't tried to get out since.
I feed him the cheapest food they have from the farm store. Still gets up and down from desks, beds, etc.
