Abstract: An animal shelter apparatus is formed as a unitary enclosure having a sidewall defining an open floor. The enclosure rests on a pair of spaced apart beams supported by a generally horizontal support surface. The sidewall is surrounded in an abutting relationship with the support surface formed as a peripheral berm. The sidewall provides two spaced apart wheels that are above the support surface when the enclosure rests on the support surface and contact the support surface when the enclosure is tilted toward the wheels.

Abstract: An enclosure provides a portal for ingress and egress of an animal and an interior environment maintenance system including a solar electric power supply, an air cleaner, a visible light emitter, an air mover, a temperature sensor, and a control unit. The control unit is enabled for receiving an ambient temperature level signal from the temperature sensor and accordingly, switching the air mover to one of: active exhaust mode, active inlet mode and standby mode.
