Prey is a Clan Term for their source of food for consumption.
Prey is used for eating, to keep the Clan up on their strength to preform clan duties. They go on specific hunting patrols to hunt prey. Each clan has a hunting territory, with their own way in hunting something. Usually, after killing a prey item, the hunter would thank StarClan for it's life. The remains (Bones, feathers, fur.) are traditionally buried. The weaker cats, elders and kits would normally be fed before warriors and apprentices, unless given special permission. Prey is much harder to find in the midst of Leaf-Bare.
