It looks as though your cat is over grooming which is causing the hair loss. The most common cause of over grooming in cats is allergies. The allergies cause skin infection and excessive itchiness. The discoloration of the skin is because of this as well. I would recommend taking your cat to the vet so the skin infection can be treated and they can give Buddy something to help with the itch.
