There are many similarities between canine and feline compulsive disorders, and the neurochemical basis for these conditions is thought to be similar across a range of species, including man. <font color="red">For a discussion of this, please see the chapter on canine compulsive disorders.</font color>

The character of the more commonly presented feline compulsive disorders appears slightly different from those in the dog and reflects the way in which the underlying motivation of arousal and anxiety reduction thought to be common in all compulsion, is expressed in behaviour that is specific to the species or breed.

Feline compulsive behaviours are generally associated with repetitious or exaggerated self-maintenance behaviour such as grooming, sucking or self-mutilation. The exception is hyperaesthesia syndrome, in which the cat responds aggressively to what may be tactile hallucinations. The behaviour in hyperesthesia syndrome is variable between cats and it is probable that a range of different aetiologies will become apparent as this condition is better understood. Indeed, it may be found to share greater aetiological similarities with oro-facial pain syndrome (seen primarily in Burmese) and feline idiopathic cystitis.

Apart from these common compulsive disorders, cats may develop compulsive behaviour that originates in a range of other activities. For example, light spot or shadow chasing, psychogenic polydipsia or polyphagia.
