Abstract: A plurality of panels preferably made from a heat insulating material define an enclosure for a pet shelter. One of the panels has an opening for the pet to enter or exit the enclosure. The panels are disposed on a base member. Detents (e.g. hooks) on the panels are removably disposed in detents (e.g. openings) in the base member to position the panels in a particular relationship on the base member. The panels may be integral with one another or may be separate. When separate, the panels may be tilted inwardly to dispose the ends of adjacent pairs of the panels in a contiguous relationship. After being tilted, the panels are joined by locking rails, each engaging the contiguous ends of a different pair of adjacent panels and each removable to disengage the panels. A top cap on the panels defines a roof for the enclosure. When the panels are integral with each other, the top cap may be integral with the panels.
