The shelter has a top panel formed from a sound-deadening material at least two flaps coupled to the top panel at least two side panels formed from a sound-deadening material, wherein each of the side panels is coupled to one of the two flaps a rear panel formed from a sound-deadening material, wherein the rear panel is coupled by an additional flap to one of the top panel or the two side panels and wherein the rear panel is removably coupled to the remaining of the top panel and the two side panels to which the rear panel is not already coupled by the additional flap. The shelter may be used as a stand-alone shelter, but it may also be placed over a pet container in order to make the container quieter.
