Do not pin the cat down or put anything in its mouth; move hard objects away, pad the area, dim the lights, and let the episode run, as most end within minutes.
Note start and end times, the seizure's form, and any drooling or incontinence, and film a clip if safe; these details are vital for the vet's workup.
A seizure over five minutes, clusters in a short window, or prolonged unresponsiveness afterward are emergencies needing immediate transport in a quiet dark carrier.
Feline seizures stem from epilepsy, toxins, hypoglycemia, or metabolic disease, so a first episode warrants a full workup soon, with no self-medication before diagnosis.
