I have two black and white rescued cats, plus two more at the school where I work. My home cats are an 8 year old long haired called Bathsheba Everdeen (from Far from the Madding Crowd)and a two year old short haired called Isolde of the White Paws ( read the story of Trystan and Isolde and find the 3 Isolde's!). As we have just moved house we have kept them in for 3 weeks and this weekend they went out on their own. They used the cat flap and came home no problem. Last nigh Isolde, whose white bits are so white they are almost blue, came home after dark, leaped up on the table, which she shouldn't have done but was so proud of finding her way home in the dark, and rolled over. There was the evidence to show she had found the calf shed in the farm next door - well not the shed itself but... the cow s***!! I really think I might have to buy cat shampoo in bulk or dye her underside a strange shade of   manure!! Even so, I love them unconditionally just as they love us unconditionally.
