There appears to be an "insert image" icon in the posting window, so i would assume it is ok to add a picture to your post. I just joined so I am not sure though.
My new little kitten Mazzy, whom I adopted from the local shelter has a spot just above/forward of her tail that keeps returning. It is really similar to a hot spot I have seen on dogs I've owned. It apparently becomes irritated and she begins to lick and chew on herself at this one location...
