There is a phenomenon known as surplus killing, where certain animals kill more prey than they need for survival. Surprisingly, it is often the predators that engage in surplus killing for various reasons, including entertainment or gaining valuable killing experience.

Orcas, also known as killer whales, are one example of animals that engage in surplus killing. They have been observed killing prey for fun, even when they have already obtained enough food. Minks are another species that occasionally exhibit this behavior.

Although surplus killing may not be considered a positive trait, it is possible that some animals seek entertainment or stimulation in this manner. Additionally, one theory suggests that by engaging in surplus killing, predators gain valuable experience that could benefit them in life or death situations when they are hungry and need to secure their next meal.

Instances have been reported where cougars, for instance, kill multiple sheep at farms without apparent reason. While such actions may be detrimental and undesirable, it is important to recognize that animals, like humans, sometimes exhibit behaviors that fulfill their innate needs, including the need for stimulation and experience.

In a notable case, a lone wolf was reported to have slaughtered 19 elk, demonstrating the extent to which surplus killing can occur in certain situations.
