No, but the stripes on my back follow an inverted chevron pattern; some stripped furries may have their stripes follow certain patterns, like tribal knotwork for example, which I see often in other Tiger characters.
Obviously, some characters may want to have designed permanently dyed into their furs to mimic the tattoos they wopuld wear in real life, which is a good idea since tattoo inked into the skin and covered over with fur would be impractical.
My early fursona, Jonathan (a male anthro shark) wore a crossed dagger and lightning bolt on his left shoulder blade and a skull with a green beret and a dagger with the words "Special Forces" on his left shoulder.
