Claim:
A modular animal enclosure comprising a base portion and a top portion attached to the base portion to form a housing with a sheltered interior and a door aperture to permit ingress of an animal into said interior, wherein the top portion is configured to be hinged to the base portion to facilitate access to the interior by pivotal movement of the top portion with respect to the base portion in a first direction by at least one hinge pin which projects through respective first hinge apertures in the base portion and in the top portion on a first side of the housing, wherein the base portion and top portion further comprise respective second hinge apertures on a second side of the housing opposite the first side so that the hinge pin can be alternately inserted through the second hinge apertures to facilitate access to the interior by pivotal movement of the top portion with respect to the base portion in a second direction, and wherein the top portion and base portions each further comprise respective flanges which form first and second interference latches on the respective first and second sides of the housing so that the first interference latch impedes initiation of said rotation in the second direction and so that the second interference latch impedes initiation of said rotation in the first direction.
