Signalment, clinical features, and gross lesions in 3 cats with meningitis and meningoencephalomyelitis associated with Pasteurella multocida infection.

Case	Age	Sex	Breed	Clinical features	Gross lesions
1	5 y	SF	American Shorthair	Recurrent ear infection, progressive neurologic signs (3-d course; lateral recumbency, stiff limbs, vocalization, anisocoria, nystagmus). Treated with clindamycin (10 mg/kg IV) and mannitol (0.5 g/kg IV). The cat had cardiorespiratory arrest.	CNS: opaque, white-to-green–tinged purulent exudate coating the meningeal surface of the caudodorsal aspect of the left cerebral hemisphere.
					Kidneys: unilateral focal chronic infarct.
2	2–3 mo	SF	Mixed breed	Upper respiratory signs, ocular discharge, neurologic signs (nystagmus, paraparesis, head tilt that progressed to lateral recumbency [unknown duration]). Treated with broad-spectrum antibiotics for the respiratory signs. The cat was found dead by the owner ~1 wk after having been introduced to its new home.	Skin: periocular yellow-to-brown crusts.
					Liver: white pinpoint foci.
3	2 mo	M	Mixed breed	Upper respiratory signs, sneezing, ocular and nasal discharge, and lethargy (unknown duration). No specific neurologic signs observed by the owner. Treated with broad-spectrum antibiotics for the respiratory signs. The cat was found dead by the owner a day after it had still been seen playing with the other kittens.	CNS: purulent exudate expanding the subdural space on the dorsal and ventrolateral aspect of the right cerebral hemisphere and interhemispheric fissure, and circumferentially around spinal cord segment C1.
					Nasal cavity and frontal sinuses were filled with mucopurulent exudate.
					Skin: periocular and nasal dark brown crusts.
					Thymus: inconspicuous.
					Intestines: mild nematodiasis (Toxocara cati).
