I'll start off by saying that when I leave Lily for extended periods of time (3 hours or so) she gets incredibly sad. Not like normal, I miss you sad, but my housemates tell me that she mopes around, won't play, and has her tail between her legs at all times. Well this has happened once before and it happened again today.. she has a mysterious scratch on the inside of her back leg! It looks almost like rug burn. I know this sounds crazy but do you think it's possible that she could be hurting herself! My housemates said something about it and I just brushed it off as silly but I've searched my room and there is nothing that she could have cut herself on! I'm sooo puzzled! The scratch isn't something I need to take her to the vet for or anything but I am going to keep an eye on it and I cleaned it with hydrogen peroxide. What would you do if you were me? Any advice is welcome!!
