As a result, a cat that is denied the opportunity to engage in hunting real prey or appropriate toys may display predatory behaviour toward other rapidly moving objects such as human feet and hands. Human shrieks and squeals increase the cat's arousal and intensify the behaviour. The behavioural sequences involved in predation are practiced and perfected through object play so that in some texts the terms '''‘misdirected play’ or ‘play-related aggression’''' are used to describe a predatory form of behaviour that occurs in the absence of any genuine prey. | As a result, a cat that is denied the opportunity to engage in hunting real prey or appropriate toys may display predatory behaviour toward other rapidly moving objects such as human feet and hands.
