Convulsions, or "grand-mal" seizures, may be caused by neurological disorders, brain injury, toxins and venom or heat stress. A cat experiencing a grand mal seizure, in which all the muscles go into spasm, usually first appears restless or anxious for a minute or two and may seek affection. Next, the cat loses consciousness, may convulse or drool for a few seconds to a few minutes and may become incontinent. If the cat is convulsing, provide gentle restraint. Although your cat may appear to be quite normal when he regains consciousness, call your vet for advice; often the veterinarian will suggest keeping him confined for a day or two under close observation. Seizures lasting more than a few minutes or several seizures in succession constitute an emergency; get to the vet quickly.
