Late onset of cerebellar abiotrophy in a Siamese cat

A late onset of cerebellar degeneration was diagnosed in a one-and-a-half-y ear-old Siamese cat. The animal had been presented with mild ataxia involvi ng all four limbs. Over the following two years, the signs gradually progre ssed to severe incoordination, a frequent tendency to fall and a head tremo r. The neurological signs were consistent with a diffuse cerebellar lesion and the cat was euthanased. Profound and diffuse Purkinje cell loss was fou nd on histopathological examination, but no aetiological agent was detected .
