DESCRIPTION OF THE PRIOR ART

A variety of pet trees have been introduced.

U.S. Pat. No. 2,894,487, issued 1959 Jul. 14, to Marvin Goldson, relates to an improved scratch post for cats and other household pets, and one of its objects is to provide a scratch post with a base on which a pile of fabric is mounted with means for detaching a used fabric covering and replacing the post with a fresh fabric covering consisting of a pre-constructed sleeve of canvas, carpeting and so forth, and an inner cushioning material to provide traction and support.

U.S. Pat. No. 3,595,209, issued 1971 Jul. 27, to Paul A. Parker, describes a household cat play and exercise post assembly of a knockdown nature which is adapted to be assembled in a stationary vertical floor to ceiling position in a room and is composed of separable wooden post sections joined in end-to-end contact by interfitting removable dowels and horizontal platforms anchored by the dowels at selected joints between the post sections that extend from a floor-engaging baseplate to a ceiling engaging top plate attached to the uppermost post section by a spring-biased dowel.

U.S. Pat. No. 4,177,763, issued 1979 Dec. 11, to Weldon R. Cook, outlines a scratching post assembly for cats, and other pets, which comprises an upright elongated post, covered with carpeting, or equivalent material, and which is detachably mounted on a base which, likewise, may be covered with carpeting, or equivalent material. The post is readily demountable from the base, and the base is formed of two hinged sections which may be folded against one another, so that the assembly may be packaged to occupy minimal space for shipping and display in retail outlets.

U.S. Pat. No. 4,803,952, issued 1989 Feb. 14, to David B. Houser, pertains to a portable shelter for small animals such as cats. The shelter is formed in modular assemblies which are readily assembled into a two story condominium having segregated toilet, resting and watching areas. The shelter provides unique territory and positive psychological reinforcement for the pet.

U.S. Pat. No. 5,275,128, issued 1994 Jan. 4, to Stephen H. Barnes, relates to an easily transportable roll up cat scratching pad with, flanges, for securing the ends to the top and bottom of a door. A flexible base member provides rollup ability and vertical support for extended horizontal pet resting or exercising platforms. The platforms include tubular tunnels and flat ledges. A frontal strap extends vertically across the apparatus for further vertical support. Carpeting may be used to cover all or part of the apparatus. Attachment devices at the top and bottom of the pad allow it to be secured to the top and bottom of structures e.g. doors.

U.S. Pat. No. 5,713,306, issued 1998 Feb. 3, to Arnold B. Johnson, defines a feline playground system with scratching, climbing, resting, playing, sleeping and observation facilities that can be easily erected or disassembled. The main assembly includes several sections and sizes of cylindrical shapes that are attached end to end via threaded internal fasteners. Once the sections are fully assembled a drop-in pressure maintaining device that is preassembled is installed at the top end together with a mobile multiple toy holder. The full assembly when installed between the floor and ceiling of a room is self-supporting and is afforded stability via the pressure derived from the pressure maintaining device.

U.S. Pat. No. 5,791,293, issued 1998 Aug. 11, to Melaney L. Northrop, relates to an animal shelter with a top shell that is shaped to resemble a natural object having an irregular surface, such as a tree stump that will blend into a natural setting. An extended floor may be attached to the base, and an extended covering may be attached to the top resembling an extension of the natural object, thus further enhancing the appearance of the animal shelter. A planter, removably seated upon the top, may be used to cultivate plants.

U.S. Pat. No. 6,152,553, issued 2000 Nov. 28, to Dale N. Wunderlich, outlines a system of modular furniture construction which includes corner posts, intermediate posts, and a corner leg converter post, which each have longitudinal slots to receive panels and a rows of equally spaced holes for retaining fasteners that hold shelves in place. Vertical bores in each end of the posts allow connecting rods to couple two or more posts vertically together. Different types of furniture may be readily assembled from these elements, including, desks, computer work stations, open shelves, entertainment centers, and so forth.

U.S. Pat. No. 6,431,119, issued 2002 Aug. 13, to Cyndi M. Beymer, describes a multi-purpose cat structure having a stored mode and a use mode which includes a hollow base with a first opening in one of four side walls and a door movable between an open position for inserting and removing a litter box and a closed position in which the first opening is substantially closed. The hollow base has a second opening for the ingress and egress of a cat or the like. A pair of vertical walls are removably attached to an upper surface of the base and an enclosed sleeping/play area, with an ingress and egress opening.

U.S. Pat. No. 6,886,495, issued 2005 May 3, to Walter G. Madden, relates to a modular, multi-level pet housing that comprises a plurality of multi-sided boxes. A plurality of tubular columns of a first length generally less than the height of the side walls and a plurality of tubular columns of a second length generally longer than the height of the side walls may be joined to each other by a coupling member. The top and bottom of each box has a hole at each corner that is sized to permit a tubular member to fit therethrough, but to prevent a sleeve member from fitting therethrough.

U.S. Pat. No. 6,892,675, issued 2005 May 17, to Paul H. Comerford, defines a cat toy for occupying a cat or functioning as a hunting decoy and includes a support structure, a motor assembly, an elongated member having a proximal end connected to the motor and a distal end disposed radially outwardly from the central axis, and an object connected to the distal end by a flexible line. The motor rotates the elongated member, thereby moving the object about the central axis of the support structure, preferably with haphazard, unpredictable movement that a cat finds enticing.

U.S. Pat. No. 7,037,170, issued 2006 May 2, to Jonathan M. Pacella, outlines a toy accessory which includes an arch and a connector attached to each end of the arch.

U.S. Pat. No. 7,040,053, issued 2006 May 9, to Brian Charles Beesley, pertains to a tiered planter apparatus for use with posts which includes a base section that is adapted to be placed on the ground and around a post. A plurality of stackable members are placed on top of the base section or on top of other stackable members. A plant support member to receive a plant, or a pot is attached to an arm which is attached to the stackable member or base section. Each plant support member is disposed at a different elevation and at a preferred radial position with respect to a plant support member that is disposed above or below it.

U.S. Pat. No. 7,040,585, issued 2006 May 9, to Huang-Yi Cheng, relates to a detachable toys bracing bracket for mounting on a playpen or a play pad. It includes a central pivot dock that has a first anchor section and a second anchor section to couple with a plurality of connection rods. Each of the connection rods is coupled with an elastic element so that the connection rods may be easily pulled and extended for mounting on the playpen or play pad, or be folded easily to facilitate carrying and storing, and to enhance safety.

U.S. Pat. No. 7,376,993, issued 2008 May 27, to Peter J. Myers, discloses a play gyms and methods of operating the same.

No. 7,770,540, issued 2010 Aug. 10, to Eric Lee Halpern, defines a collapsible and scaleable floor to ceiling post forming an exercise and perch system for domestic cats using integral platforms that function as steps and perching areas. The post may be adjusted to different ceiling heights by adding or removing interchangeable sections and provides fine adjustment with a telescopic section that is spring biased to limit forces on the ceiling.

U.S. Pat. No. 7,832,361, issued 2010 Nov. 16, to Tracey Stevens, pertains to a system for climbing pets, particularly cats, featuring an expandable rod and an array of wall supports, platforms and accessories.
