Survival of a cat with pneumonia due to cowpox virus and feline herpesvirus infection.

Cowpox virus infection in cats is rare and usually leads to cutaneous lesions alone. Pulmonary infection and pneumonia have been documented occasionally but all such cases described to date have been fatal. Although usually affecting the upper respiratory tract, feline herpesvirus can also induce pneumonia. The present report describes the case of a cat that recovered from a pneumonia in which both poxvirus and feline herpesvirus were demonstrated.
