Despite being domesticated, cats retain remarkable hunting skills, often seen chasing rats and birds near their homes. Because of this, felines are considered one of the main threats to global avifauna. However, these animals do not always consume their prey after capturing it, raising the question of why this behavior occurs.
To understand this phenomenon, it is essential to recognize that, in feline perception, the predatory impulse and nutritional need are not intrinsically linked. A scientific analysis conducted in 2021 highlights this distinction between the motivation to hunt and the requirement to obtain food. The authors point out that cats with guardians and who receive domestic food no longer need to hunt, but they retain this instinct as an 'influence inherited from their wild ancestors.'
Additionally, the hunting instinct is not entirely dependent on the feeling of hunger. Hunting constitutes a series of actions—locating, pursuing, grabbing, and biting—that does not necessarily culminate in the ingestion of the prey. An experiment conducted in 1976 was performed to verify this hypothesis: six cats were kept without nutrition for 48 hours and subsequently had access to their favorite foods. While eating, scientists released a rat into the environment. All the cats, except one, interrupted their meal to hunt the rat.
Subsequently, the cats brought the killed rat close to the feeding area. However, most opted to continue eating the provided food rather than the captured rat. As the study's researchers indicated, these results suggest two points: firstly, that the predatory inclination is more prominent than the need for food consumption; and secondly, that the act of eating does not have to be the final phase of the predation process, although hunger can intensify such action.
Research indicates that domestic cats tend to specialize in their favorite prey and may seek them even when other types of prey are available. For example, a cat that shows a preference for rats may disregard the birds around it. This means that the act of hunting is not necessarily linked to the search for sustenance.
Another relevant factor to consider is that hunting can also be a form of play. This is observable in domestic environments, where the cat chases toys, attacks, and bites objects, even if these are not real prey (there is even evidence that playful interaction with objects aids in partially satisfying the predatory motivation). When a cat manages to capture a real prey and starts releasing it, chasing it again, or manipulating it, a playful element may be involved. Although researchers agree that play and hunting are distinct behaviors, it is noted that they intersect in various aspects.
In summary, although it seems contradictory to hunt an animal without the intention of consuming it, it is necessary to accept that, for cats, this behavior has meaning. The act of hunting is fulfilling other needs and instincts, and not exclusively the search for food.
