Seizures in Cats

Schriefl, S., T. A. Steinberg, et al. (2008). “Etiologic classification of seizures, signalment, clinical signs, and outcome in cats with seizure disorders: 91 cases (2000-2004).” J Am Vet Med Assoc 233(10): 1591-7.

Epileptic seizures can occur in cats for many reasons, such as metabolic or toxic conditions, inflammatory or infectious diseases, or neoplasia. Seizures with no identifiable cause are called idiopathic epilepsy, which has been considered rare in cats. The purpose of the study reported here was to evaluate associations among etiologic classifications of seizures and signalment, clinical signs, and outcome in cats with various seizure disorders. In this retrospective case series, data was collected on 91 cats presented for seizure disorders to Ludwig-Maximilians University in Munich from 2000 to 2004. During this period, the incidence of seizures in all cats presented to this hospital was 2.1%. Etiology was classified as reactive in 20 (22%) cats, symptomatic in 45 (50%), idiopathic or presumptive idiopathic in 23(25%), and cardiac syncope in 3 (3%). Focal seizures were recorded in 52% of the cats, and generalized seizures in 48%. The mean age of cats with idiopathic seizures (3.5 years) was significantly lower than that of cats with reactive seizures (8.2 years) or symptomatic seizures (8.1 years). Cats with idiopathic seizures survived the longest.
