A wildlife containment system includes a first modular unit positionable on a surface and configured to contain a first wildlife habitat, the first modular unit including a first set of outer supports located at corner regions of the first modular unit, a second modular unit configured to contain a second wildlife habitat, the second modular unit including a second set of outer supports located at corner regions of the second modular unit, and a support structure received within apertures in the first and second sets of outer supports, the support structure maintaining the first and second modular units in a fixed relationship such that the second modular unit is supported at least in part by the first modular unit and suspended above the surface.
