Thumper has been free ranging indoors for 3 1/2 years, has very furry feet, but I check his hocks when I clip his nails. He used to lie "flopped out" on his side, most of the time, but since his fright doesn't do so. This evening I found both hocks have lost fur, but it's hidden by surrounding fur overlying the area. The skin on 1 is a little inflamed but not infected.
