Always call your veterinarian Wake Forest, NC if you notice your Himalayan cat having convulsions, fits or uncontrollable body movements. Your cat may be suffering from epilepsy. Feline epilepsy is a brain disorder that can cause your cat to have sudden, uncontrollable seizures. Many experts believe the seizures occur due to a confusion of neuron firings in the cerebrum of the brain. The cause for the confusion is unknown. Suggested causes for the seizures; however, may include congenital defects, diabetes, hypoglycemia, low oxygen levels in the blood, kidney disorders, liver disorders, infections, brain tumors, toxins, fevers, hyperthermia, trauma, medications, or idiopathic epilepsy (genetic disorder). Although the triggers for a seizure are not known, it is believed that cats at risk are more prone to seizures when they are excited. Some cats; however, have had seizures in their sleep. If your cat has any of the conditions listed above and has suffered from recent seizures, inform your vet.
