Surplus killing is the behavior predators exhibit when they kill more prey than they can immediately use. They may partially consume, cache, or abandon intact prey. This behavior has been observed in zooplankton, damselfly naiads, predaceous mites, weasels, honey badgers, wolves, orcas, red foxes, spotted hyenas, spiders, brown bear, lynx, mink, and house cats.
