Fascinating Feline Facts. I found that page while researching how cats purr. (Answer: Nobody really knows. There are a number of theories.) There’s a lot of weird facts in there I didn’t know, like how white cats with blue eyes are deaf and only female cats can be both black and orange. Apparently “cats respond most readily to names that end in an “ee” sound,” so we lucked out with her name. Also, it says that tortoiseshells are “black with red or orange markings” and calicos are “white with patches of red, orange and black.” That makes Amy a calico. I wonder if that’s an American term or something, because the Cat Protection Society definitely had her down as “tortoiseshell-and-white.”
