Naturally occurring scrapie-like spongiform encephalopathy in five domestic cats
Naturally occurring transmissible spongiform encephalopathies have been recognised in sheep, man, mink, captive deer and cattle. Recently a similar disease was reported in a domestic cat. This paper describes the clinical and pathological findings in five cats with similar signs, including further observations on the original case. All the cats had a progressive, neurological disease involving locomotor disturbances, abnormal behaviour and, in most cases, altered sensory responses. Histopathological examination of the central nervous system revealed changes pathognomonic of the scrapie-like encephalopathies, including widespread vacuolation of the grey matter neuropil, vacuolation of neuronal perikarya and an astrocytic reaction.
