It’s not easy to catch an adult strong predator, but it’s quite possible to lure kids with something tasty, which is what happened in Trapped Wolf Rescue. The little wolf cub apparently got caught this way and is now sitting in a cage with no way to get out on his own. There is no visible keyhole on the cage, which means you need to look for some object that will be the key to the door. Examine everything you find nearby, find the key to the door to a small hunting lodge. Perhaps it contains what you need in Trapped Wolf Rescue.
