A convulsion is the violent irregular motion of limbs or body caused by involuntary contraction of muscles.
Common signs are loss of consciousness, incontinence and vocalisation.
Other terms that may be used are seizures or fits, with Epilepsy confined to disorders characterised by repeated fits of unknown origin. The most common type of convulsion is known as Idiopathic Epilepsy, the cause of this is unknown. It is usual for a fit to last several seconds only. Approach the animal with care. Roll your pet onto a blanket away from furniture and drag clear from any possible harm such as an open fire.
