In domestic carnivores periodontal disease is universally very common due to host response and dietary reasons.
In Europe, the Middle and Far East, periodontal disease in zoo carnivores is rare due to the relatively natural self cleansing diet they are fed on. North American establishments frequently feed their carnivores a soft, "predigested" diet, that has no self cleansing properties.
Hence the animals often suffer with periodontal degeneration.
