  • Publication number: 20060272592
    Abstract: A squirrel house that can be used for shelter from predators, from cold weather and for providing a den for a breeding pair of squirrels to build a nest for raising a family of young squirrels, having a front wall including a side access hole, a floor having a bottom access opening, a pair of matching side walls supporting a shed roof end extending at a slight incline from the back wall to and over the side access wall being supported along the tapered top edges of the side walls. The squirrel house also employs multiple predator guards including a predator guard mounted on the roof, an internal predator guard, an interior baffle to reduce access by a predator, and a roof guard comprising projections on the roof to hinder predator access from the roof, and where there is a separate exit hole for the nesting squirrel(s) to exit while a predator attempts to enter through a predator guard hole.
