A chamber for separating visual and physical prey access from predators

A chamber is described that provides automated separation of various phases of depredation dynamics. Two solenoid actuated doors control visual and physical access to prey items. A lever operandum is programmable to require differential response outputs by the predator. Search lever responses open one door and allow detection which may then be followed by pursuit lever responses and ultimate access for capture. The chamber is suitable for such medium sized predators as foxes and coyotes.
