so ive had my bp for about 2 n ahalf months and hes been fine but recently ive notice that he looks like hes loss weight. hes eating fine so i dont know why he looks like it and he just finished his second shed so i dont know if hes just growing or if hes losing weight for some reason.also his skin wrinkles up when his bodys turned alot, i read that this is a sign that hes under weight..
