A pet enclosure includes a cover and a support frame. The cover includes a bottom panel, a top panel opposite the bottom panel, and a plurality of side panels extending between the bottom panel and the top panel to define an interior space of the cover. An aperture is defined in at least one of the top panel and one of the plurality of side panels for accessing the interior space. The support frame is pivotable between a collapsed configuration and an upright configuration and is insertable into the interior space of the cover through the aperture in the collapsed configuration of the support frame. The support frame is also pivotable from the collapsed configuration to the upright configuration while disposed within the interior space of the cover.
