The cat suddenly twitches all over and then becomes fine. This situation may be caused by a variety of reasons. Here are some possible explanations: Epilepsy: Epilepsy is a common neurological disorder in cats that can cause sudden convulsions. The twitching may last from seconds to minutes and then resolve on its own. If your cat has frequent convulsions, it is recommended to go to a pet hospital for diagnosis and treatment. Poisoning: Cats may be poisoned by accidentally ingesting toxic substances, causing damage to the nervous system and causing convulsions. In this case, you should take the cat to the pet hospital immediately so that the veterinarian can perform detoxification treatment.

Electrolyte metabolism disorders: such as hypocalcemia, alkalosis, etc. may cause damage to the stability of the cat's nerve cell membrane, thereby causing convulsions . At this time, the cat’s diet needs to be adjusted and corresponding electrolytes supplemented.

Stress response: Cats may have a stress response when they are strongly stimulated or frightened, manifesting as brief convulsions. This twitching is usually physiological and does not require special treatment, but care needs to be taken to avoid re-irritating the cat.
