“…For example, nutritionally induced type 2 diabetes with possible cataract formation was described in the fat sand rat (Psammomys obesus); 31 a genetic component seems to be involved because different genetic lines of Psammomys obesus can be generated that differ in their proneness to dietinduced diabetes. 16,18 A diet-induced diabetes mellitus with cataract formation is described also in degus (Octodon degus) 7 , while a genetic etiology is suspected in Chinese hamsters (Cricetulus griseus) 12 and chinchillas (Chinchilla lanigera) 10 . Additionally, viruses associated with a type 1 diabetes-like syndrome have been described in several rodent species e.g.…”

Occurrence of cataract and fatty liver in captive plains viscachas (Lagostomus maximus) in relation to diet Abstract An increased incidence of cataract and fatty liver in plains viscachas (Lagostomus maximus) was noted for many years at the Zurich Zoo. Based on elevated serum fructosamine and glucose, diabetes mellitus was diagnosed, and these parameters normalized when the diet of the animals was changed from a low-fiber to a high-fiber diet. Here, we evaluate 177 necropsy reports from before and after the diet change for the incidence of cataracts and fatty liver. Sixteen of 56 animals (29%) that were born before the diet change developed cataract. In contrast, only two of 121 animals (1.65%) that were born after the diet change developed cataracts. The prevalence of cataract and fatty liver in animals born after the diet change (1% and 0%, respectively) was significantly lower than in animals born before (9% and 6%, respectively) the diet change. The results suggest that the plains viscachas at Zurich Zoo were affected by an alimentary induced diabetes mellitus (type 2) before the diet was changed.
