Would some body know why my domestic short hair house cat is losing her fur on the back of her front legs and on her belly? This is concerning me. I have one other cat and he is fine. We recently moved in with a dog so I thought it might be stress but I'm not sure. She always had this small patch of exposed skin on the back of her front leg and I thought she was doing it to herself because sometimes it would look really raw and red and then sometimes it would look like it was healing and now these big patches look really red sometimes too. I have no idea what could be causing this! Please help!
