Feline seizures are primarily caused by factors such as dreaming, calcium deficiency, encephalitis, toxoplasmosis, epilepsy, or poisoning. Generally, if the seizures are simply due to dreaming, it's a relatively normal phenomenon, and owners can soothe the cat to help it calm down on its own; there's usually no need to worry excessively. However, if the cat experiences headaches, foaming at the mouth, or other symptoms during seizures, it's recommended to take the cat to a reputable veterinary clinic for a thorough examination, as this will help promote recovery.

Of course, if a cat experiences convulsions due to calcium deficiency, then pet owners should supplement its calcium intake regularly.
