Periodontal disease: Dirty teeth, bleeding gums, loose or missing teeth, avoidance of touch near mouth and cheeks; lackluster or oily coat, dandruff, excessive shedding, bad breath. These could be signs of other illnesses, as well (cats should never have bad breath).

Sometimes the cause is competitive eating in multicat households. |
