A cluster of cases of feline dysautonomia (Key-Gaskell syndrome) in a closed colony of cats.

Twenty-five cases of feline dysautonomia (Key-Gaskell syndrome) occurred in a closed cat colony over a period of three weeks. The clinical and pathological signs were sufficiently similar to those reported during the 1982-1986 outbreak to establish a positive diagnosis. The special epidemiological and environmental circumstances of the outbreak provide a new insight into the cause(s) of the syndrome.
