Cystic renal disease in the domestic ferret.

Cystic renal diseases in domestic ferrets are a common anecdotal finding but have received scant systematic assessment. We performed a 17-y, case-control retrospective analysis of the medical records of 97 ferrets housed at our institution between 1987 and 2004, to determine the prevalence and morphotypes of cystic renal diseases in this species. Histologic sections stained with hematoxylin and eosin, Masson trichrome, or periodic acid-Schiff were evaluated by a comparative pathologist, and statistical analysis of hematologic and serum chemistry values was correlated with morphologic diagnosis.

Acute paraplegia in a young adult long-evans rat resulting from T-cell lymphoma.

We describe an unusual case of acute paraplegia in a young adult (7.5-month-old) Long-Evans rat that resulted from a spontaneous T-cell lymphoma. At presentation, a neurologic exam revealed normal pelvic limb flexor reflexes, the absence of an anal reflex, and deep pain recognition.
