I have a cat called Tink. She is 6 years old, and she has a sort of.. pattern, if you'd like to call it by that, on her part by her tail. I thought it was a bald patch at first, but I looked up images of the bald patches and it doesn't look like one.
I have a picture, sorry for the bad quality.
Does ANYBODY know what it is? How did it come up?
