because of how the model is formed, unfortunately they do not go straight. X3 You know the UV references you get in your preset folder? Open the one for the body as a new layer (F or C depending on feline or canine) and where the lines are by the legs, for the stripes, follow the horizontal lines across there. The stripes will look mis-shaped and different sizes, but on the model, they will look even. If you need a picture showing what I mean I can make one for ya cause I can't explain well. xD
