Hey man. I shot a half white fox squirrel last september. Just picture the top half of a foxy bn white and bottom regular colors. He was a old foot I tell ya. Had a set of plums on him lol. Head was white, ears regular and almost like he had a mask on, of regular colours n the face. Love to email u a pic. I live in Alton il my self and we dont have any white tree rats. The 1 I got was the only iv seen, among other people as well. The city that the whites do live in is spelled and pronounced very similarly to Alton. I'm not tryin to be rude or question you in any way man.
