The most common things that could cause this behavior are flea bites around the back or tail, anal sacs that are full and itchy or infected, or a tail injury. You can check for fleas by combing the fur with a fine tooth comb. If you see fleas on the comb then give a bath and apply a flea prevention product. If you see him scooting I recommend your veterinarian express the anal sacs to empty the fluid and see if there is an anal sac infection. You can feel his tail and if there is a tail injury there will be one area that is more sensitive. Usually tail injuries will heal without treatment over a few days.
