Changes

Expectations are conditioned by previous experience, with the strongest emphasis on experience gained during the [[Feline Socialisation|sensitive period]]. Anecdotally, there is an association between hand rearing and frustration-related aggression. During weaning, mothers progressively withhold an increasing proportion of milk, leaving the offspring frustrated and driven to seek other sources of food. Hand fed kittens are often fed to satiation, so that this early experience of frustration does not occur. This type of feeding may lead to  '''inappropriate expectations''' about feeding and human contact.

==Diagnosis==

==Investigation==

'''Frustration occurs when an anticipated event does not happen or fails to meet the individual’s expectations'''. For example when the owner does not open a door or a can of food quickly enough or when a person tries to walk away from a cat when it expects interaction to continue. Often the aggression is not an isolated behaviour and the cat also displays '''other frustration-related behaviours''', such as excessive vocalisation or [[Indoor Marking - Cat|indoor marking]] in situations where it appears to be thwarted by circumstance. Frustration-related aggression may be made worse if motivation is abnormally increased by illness. For example, in cats that are suffering from polyphagia due to [[Hyperthyroidism|hyperthyroidism]] or [[Diabetes Mellitus|diabetes mellitus]]. There is also usually a history of hand rearing or a pattern of regular reinforcement of demanding behaviour throughout the cat’s life.
