Pre-ictal phase

• Your cat may hide when she feels a seizure coming on.cat 6 image by Galyna Andrushko from Fotolia.com
  
  Before the next seizure comes on, your cat may act as though something is "not right." Dr. Ernest Ward of the Wignall Animal Hospital System in Massachusetts describes such behavior as nervousness or refusing to leave your side. This phase can last a few minutes to a few hours.
  
  

Ictal phase

• During a seizure, your cat will fall over; make sure she is safely on the ground and then back away.cat image by Dwight Davis from Fotolia.com
  
  During the actual seizure your cat's muscles will tense and spasm. This may appear as a violent twitching or one long, rigid bend. The disruption to the system will cause your cat to collapse and, most likely, to lose control of bladder and bowel function.
  
  

Post-ictal phase

• Confusion and aggression often follow a seizure.cat image by Dwight Davis from Fotolia.com
  
  Afterward, your cat will have no memory of the event, be disoriented and behave nervously. Your cat may not recognize you or behave in a hostile manner. Be patient with your cat and remember the ordeal that has just taken place.
  
  

Causes

• Genetic factors, environmental causes or trauma can engender seizure activity.the cat image by Norbert Tuske from Fotolia.com
  
  Virtually any disease process that interferes with brain function can result in seizures. Epilepsy is usually the culprit; infections, injuries, or tumors are less often the cause. Your vet can perform simple blood and imaging tests to determine the source of your cat's symptoms.
  
  

Prevention

• Seizures may seem frightening, but they rarely result in any lasting damage to your cat.cat image by petar Ishmeriev from Fotolia.com
  
  Your vet may prescribe oral anti-convulsive medications to reduce or eliminate your cat's seizures. In the rare instance that a more serious problem lies at the root of the symptoms, more aggressive therapy or surgery may be necessary.
