Two tree shrews with bilateral cataracts, a male and a female from a colony of six in captivity for more than a year, were found to have diabetes mellitus. The male died before his condition was controlled with insulin and restrictive diet.

In the female there was diffuse fibrosis with replacement of nearly all of the islet cells.
