Play behavior in cats is a hunting behavior substitute that requires regular provision to meet the behavioral needs of indoor cats, with important welfare implications when neglected.
Cat play behavior is not a luxury but a welfare necessity for indoor cats whose predatory drive is not expressed through hunting. The critical element is allowing the full predatory sequence including the capture moment - abruptly ending play before this point causes the frustration equivalent of repeatedly interrupting a meal before it is finished. Wand toy play that simulates prey movement, culminating in successful capture, provides behavioral satisfaction that significantly improves indoor cat welfare.
