one of my girls has just had a sore leg, i noticed her limping slightly but more so when she would run about she would like skip, and when standing would lift the leg more than normal, i rang the vet and he said leave it a couple of days, i had thoroughly checked the legs for swellings and heat, scratches cut, underside of the foot, claws and could see absoutley nothing so left her and sure enough she was fine in a few days. nickyx
