The shelter offers protection from predators; if one tries to enter, the two separate openings ensure that the toad always has an escape route. The openings measure 2-3/4" high by 4" wide, large enough for most common North American toads. Two small holes in the roof permit ventilation and help prevent rainwater from pooling on top.
Store indoors during winter, as freezing temperatures may cause breakage. This small investment in low-rise housing gives a big return.
