Non-suppurative encephalomyelitis in cats suggestive of a viral origin

In 10 of 16 domestic cats with spontaneous non-suppurative encephalomyelitis, lesions were multifocal but relatively few and were considered nonspecific as to cause, although viral agents could not be excluded. Six cats had polioencephalomyelitis or polioencephalitis suggestive of viral infection. The clinical and morphological features are compared with those of previous reports of feline encephalitis possibly of viral origin. Some previously reported epidemiological and serological surveys suggest a possible role for arboviruses.
