Found these in our backyard the other day in Greenville, sc. Fenced in backyard. Whatever it is can jump fences bc they pick up on the other side. I see bigger ones (about 3.75 inches long by 3 in wide) and smaller ones. Thinking fox or coyote? Anyone have any thoughts? Thanks arbrowncu@gmail.com guess it won't let me attach pictures so those that can identify tracks please email me
