     Description of Illustrated Embodiments 
     Now turning to the drawings,  FIG.  1    shows a side view of an improved structure ( 100 ) having a post ( 110 ) with a first post section ( 111 ) and a second post section ( 112 ). The first post section comprises a first proximal end ( 116 ) and a first distal end ( 117 ) opposite the first proximal end. The second post section comprises a second proximal end ( 118 ) and a second distal ( 119 ) end opposite the second proximal end. The first proximal end of the first post section is coupled to a base ( 400 ). The first distal end is coupled to the second post section at the second proximal end. An optional median elevated surface (not shown) can be disposed between the first and second post sections. The second post section is coupled to a first elevated surface ( 130 ) at the second distal end. The first and second post sections each comprise a hollow interior ( 114 ). 
     As shown, means for coupling the first post section ( 111 ) with the second post section ( 112 ) is accomplished by a post coupler ( 200 ). The post coupler comprises a male subcomponent ( 201 ) and a female subcomponent ( 202 ). The male subcomponent comprises a male body ( 203 ) and a male connector ( 204 ) coupled to the male body. The female subcomponent comprises a female body ( 205 ) and a female connector ( 206 ) coupled to the female body. The male subcomponent is coupled to the second post section at the second proximal end ( 118 ) and the female subcomponent is coupled to the first post section at the first distal end ( 117 ). In other embodiments, the male subcomponent is coupled to the first post section and the female subcomponent is coupled to the second post section. 
     The first post section ( 111 ) is coupled to the base ( 400 ) by a base coupler ( 250 ). The first post section comprises a female portion ( 252 ) disposed with the first post section at the first proximal end ( 116 ). The base coupler comprises a male thread ( 250 ) configured to attach to the female portion. The female portion is disposed within the hollow interior ( 114 ) of the first post section. In embodiments, the first post section comprises a male portion and the base coupler comprises a female thread for engaging with the male portion. The base coupler ( 250 ) can additionally include arms ( 253 ) coupled to a surface of the base. The arms increase strength and support of the first post section with the base. Each of the arms can include a fastener aperture for increasing the coupling strength. In some embodiments, the male or female portion coupled to and disposed within the first post section is the same or similar male subcomponent ( 201 ) or female subcomponent ( 202 ) of the post coupler ( 200 ). 
     The post couplers ( 200 ) and base coupler ( 250 ) provide an advantage of securely coupling modular post sections while having an aesthetically smooth surface for climbing. Many kinds of posts are manufactured with outer diameters having low tolerances but inner diameters having high tolerances. One reason is because posts normally used for animal structures are pipes or tubes used in plumbing where coupling of said pipes or tubes occurs at an exterior thereof. Using a coupler disposed inside the hollow interior ( 114 ) can therefore be challenging given the variance of inner diameters between post sections. 
     Post couplers ( 200 ) disposed within the first and second post sections ( 111 ;  112 ) may have the male body ( 203 ) or female body ( 205 ) having an extended length which expands further into each of the post sections. This allows for a stronger coupling by preventing movement in the x and y directions. 
       FIG.  2    shows a side view of a post ( 110 ) with a post coupler ( 200 ) disposed therein according to the first illustrated embodiment. More specially, the post is a second post section ( 112 ). The post coupler comprises a male subcomponent ( 201 ) having a male body ( 203 ). The male body comprises a male outer periphery ( 207 ). Coupled to the male body is a male connector ( 204 ) being a male thread ( 230 ). The male thread is configured to couple with a corresponding female thread. The male body comprises a plurality of apertures ( 222 ) and a plurality of ridges ( 221 ) disposed on the male outer periphery. Each of the plurality of apertures is configured to receive a fastener (such as a screw, bolt, nail, dowel or other known types of fasteners) wherein said fastener extends through the post and engages with one of the plurality of fasteners, thereby securing the male body to an inner wall ( 113 ) of the post. The plurality of ridges allows the post couplers to fit and align in posts having various sized inner diameters. The plurality of apertures allows the male subcomponent and female subcomponent to attach to the post. 
     The male subcomponent ( 201 ) of the post coupler ( 200 ) is disposed within a hollow interior ( 114 ) of the post ( 110 ). The male subcomponent is fully disposed within the hollow interior such that it is deep enough inside the post that the male body ( 203 ) is disposed below an opening ( 115 ) of the post. This ensures that the post remains flush between the junction of the first and second post sections. 
     The post ( 110 ) comprises holes (not shown) which align with the apertures ( 222 ) of the post coupler ( 200 ) to allow for easy alignment and insertion of fasteners. Preferably, the apertures of the post coupler and the holes of the post may comprise an amount of three or more. In a preferable embodiment, the spacing between the apertures and corresponding holes are evenly spaced such that an amount of three apertures is spaced one hundred and twenty degrees spaced, an amount of four apertures is spaced ninety degrees apart, etc. 
     The plurality of ridges ( 221 ) is semi-flexible which allows for conforming to the inner wall ( 113 ) when fitting post couplers ( 200 ) to the post ( 110 ). Semi-flexibility of the plurality of ridges can be achieved by design of material and/or a thickness ( 221 ) of each ridge thin enough to achieve the desired semi-flexibility. Semi-flexibility can be done with certain kinds of thermoplastics such that the plurality of ridges comprises a same material as both of the male body ( 203 ) and the female body. The plurality of ridges assists in ensuring a proper fit of the post coupler with a post having a variable post inner diameter. 
       FIG.  3    shows a side view of a post ( 110 ) with a post coupler ( 200 ) according to the first illustrated embodiment. The post comprises a first post section ( 111 ) having a first distal end ( 117 ) and a second post section ( 112 ) having a second proximal end thereof. The post coupler comprises a male component ( 201 ) and a female subcomponent ( 202 ). The male subcomponent comprises a male body ( 203 ) having a male outer periphery ( 207 ). Coupled to the male body is a male connector ( 204 ) where the male connector comprises a male thread ( 230 ). The female subcomponent comprises a female body ( 205 ) having a female outer periphery ( 208 ). The female subcomponent further comprises a wall extension ( 241 ) extending from a perimeter of the female body, wherein a female connector ( 206 ) is disposed within the wall extension. As shown, the female connector is a female thread ( 240 ). 
     The post couplers ( 200 ) are configured to be disposed and coupled to a hollow interior ( 114 ) of the post ( 110 ) wherein the male body ( 203 ) and female body ( 205 ) are configured to contact an inner wall ( 113 ). The male body of the male subcomponent ( 201 ) is configured to be inserted first so that the male connector can protrude from an opening ( 115 ) of the post. As shown, the first post section ( 111 ) is configured to receive the female subcomponent ( 202 ) and the second post section ( 112 ) is configured to receive the male subcomponent. Once both male and female subcomponents are coupled with their respective post sections, the male and female connector ( 204 ;  206 ) can then engage each other until the first and second post sections are flush. This forms a post with a uniform body free from external attachments disposed on an outer surface of the post. 
     Disposed on both the male body ( 204 ) and female body ( 205 ) is an aperture ( 222 ). The male and female bodies may each comprise a plurality of apertures. A corresponding hole on each post section is made to align with one of the plurality of apertures. 
     The male connector ( 204 ) and the female connector ( 206 ) are shown as being a male thread ( 230 ) and a female thread ( 240 ). In alternative embodiments, other fastening mechanisms can be used as can be appreciated by one having skill in the art. In one embodiment, a friction fit can be utilized. 
       FIG.  4 A  and  FIG.  4 B  show a post coupler ( 200 ) used to couple to a post ( 110 ) according to the first illustrated embodiment. The post coupler comprises a male subcomponent ( 201 ) and a female subcomponent ( 202 ). The female subcomponent comprises a female body ( 205 ) having a plurality of apertures ( 222 ) disposed thereon. The male subcomponent comprises a male body ( 203 ) also including the plurality of apertures. The male subcomponent further comprises a male connector ( 204 ) configured to fit within a female connector ( 206 ) of the female subcomponent. Once the male subcomponent is fully engaged with the female subcomponent, the post becomes flush. 
       FIG.  5    shows perspective view of an improved animal structure ( 100 ) according to an embodiment. The animal structure comprises a post ( 110 ) extending from a base ( 400 ). The base is coupled to a stability platform ( 120 ). The post comprises a first post section ( 111 ) and a second post section ( 112 ). The first post section extends through the base and couples to a bottom portion ( 401 ) thereof. The second post section couples to an opposite end of the first post section to increase height of the overall post. Disposed between the first and second post sections is a median elevated platform ( 140 ). Disposed on an opposite end of the second post section is an upper elevated platform ( 130 ). The base comprises the bottom portion, a front portion ( 402 ), a back portion ( 403 ), and sides portions ( 404 ). The base may also comprise optional openings for providing inside access to animals. Located where the median elevated portion meets the first and second post sections is a stabilizer system ( 300 ). 
       FIG.  6    shows side view of a stabilizer system ( 300 ) according to a second illustrated embodiment. The stabilizer system comprises first stabilizer component ( 310 ) and a second stabilizer component ( 320 ). The first stabilizer component is coupled to an exterior of a first post section ( 111 ) and the second stabilizer component is coupled to an exterior of a second post section ( 112 ). The first and second stabilizer components may couple to the exterior of the post sections by glue, nails, or other means which can be appreciated by one having skill in the art. Disposed between the first and second stabilizer components is a median elevated platform ( 140 ). The median elevated platform comprises a first surface ( 141 ) and a second surface opposite the first surface ( 142 ). The first stabilizer component is coupled to the first surface and the second stabilizer component is coupled to the second surface. 
     The stabilizer system ( 300 ) comprises a first fastener aperture ( 311 ) extending entirely through the first stabilizer component ( 310 ) and the median elevated ( 140 ). The first fastener aperture further extends partially into the second stabilizer component ( 320 ) such that a fastener disposed within the first fastener aperture does not protrude through the second stabilizer component. The stabilizer system further comprises a second fastener aperture ( 321 ) extending entirely through the first stabilizer component and the median elevated. The first fastener aperture further extends partially into the second stabilizer component such that a fastener disposed within the first fastener aperture does not protrude through the second stabilizer component 
     When the median elevated platform ( 140 ) is not present between the first and second stabilizer components ( 310 ;  320 ), a fastener of shorter length can be used to couple the first stabilizer component directly with the second stabilizer component, thereby increasing surface area between the first and second post sections ( 111 ;  112 ). The increased surface area increases strength at the joint which can be advantageous when weight is applied at an upper elevated platform ( FIG.  5   ;  130 ) disposed above the stabilizer system ( 300 ). If the median elevated platform is present, corresponding apertures extending through the median elevated surface are located to align with both the apertures of the first stabilizer component and the second stabilizer component. 
     Coupling each of the first stabilizer component ( 310 ), the second stabilizer component ( 320 ), and the median elevated platform ( 140 ) together increases integrity when weight is applied to the upper elevated platform, the median elevated platform, or both. When the median elevated surface is disposed between the first and second stabilizer components, a fastener of greater length will be used. 
       FIG.  7 A- 7 C  show a modular base ( 400 ) according to a third illustrated embodiment. The base comprises a bottom portion ( 401 ), top portion (not shown), front portion ( 402 ), back portion ( 403 ), and side portions ( 404 ).

     The bottom portion ( 401 ) comprises two guides ( 411 ) disposed on opposite ends, in addition to male attachments ( 412 ) disposed on each corner. The front and back portions ( 402 ;  403 ) each comprise guide receivers ( 414 ) and female attachments ( 413 ) such that the guide receivers are each configured to receive one of the guides and the female attachments are each configured to receive one of the male attachments from the bottom portion. The top portion is coupled to the front and back portions in a similar fashion. 
     The front and back portions ( 402 ;  403 ), in addition to the side portions ( 404 ), comprise a connecting mechanism ( 410 ) for coupling the side portions to the base ( 400 ). The connecting mechanism may comprise a male and female insert, a hook and latch, or other mechanisms that can be appreciated by one having skill in the art. 
     The female attachments ( 413 ) coupled to the front and back portions ( 402 ;  403 ) may comprise a rectangular or semi-circle shape, but is preferable to have a flat surface for proper coupling to said front and back portions. 
     The male and female attachments ( 412 ;  413 ) may comprise holes for fasteners. The guides may not comprise such holes and instead are used to ensure proper alignment and increase structural integrity. It can be appreciated that holes on the female attachment are equal to or greater than holes on the male attachments to ensure sufficient clearance for a fastener. 
       FIG.  8 A- 8 C  show a collapsible base ( 400 ) according to a fourth illustrated embodiment. The base comprises a front portion ( 402 ), a back portion ( 403 ), a bottom portion ( 401 ), a top portion ( 425 ), a two side portions ( 404 ). The front and back portion comprise a hinge or crease at a corresponding midsection ( 422 ) to allow the front and back portions to fold in half, causing the top portion to collapse on top of the bottom portion. The sides portions are hingedly coupled to the top portion by a first hinge ( 423 ) and second hinge ( 424 ), and are configured to rotate from the top portion when in a collapsed state ( 420 ) to the bottom portion when in an expanded state ( 421 ). In other embodiments, the side portions are hingedly coupled to the bottom portion and rotate upwards towards to the top portion. 
     The bottom portion ( 401 ) comprises stoppers ( 427 ) where each stopper is located near an edge of the bottom portion. The stoppers are configured to prevent the side portions ( 404 ) from rotating outwards from the bottom portion. After the base ( 400 ) has been put into an expanded state ( 421 ) with side portions rotated downward, a support bar ( 426 ) can be installed inside the base at the bottom portion to prevent the side portions from rotating into a collapsed state ( 420 ). Each of the side portions is held in place by the stopper on one side and the support bar on the other, thereby creating a rigid expanded structure. 
       FIG.  9    shows a perspective view of the post coupler ( 200 ) in accordance with a fifth illustrated embodiment. The post coupler comprises a male subcomponent ( 201 ) and a female subcomponent wherein the male subcomponent is configured to attach to the female subcomponent. The female subcomponent comprises a female body ( 205 ) with a wall extension ( 241 ) extending from the female body. Disposed on an inner surface of the wall extension is a female connector ( 206 ). The male subcomponent comprises a male body ( 203 ) with a male connector ( 204 ) extending from the male body. The male connector is configured to couple with the female connector. One or more apertures ( 222 ) is disposed on the male body and female body for connecting with a corresponding post. 
     The male subcomponent ( 201 ) comprises a material having a subcomponent density ( 209 ). Extending longitudinally through both the male body ( 203 ) and the male connector ( 204 ) is a cavity ( 210 ). Disposed within the cavity is a core support ( 211 ) having a core density ( 212 ). In some embodiments, the core support occupies an entirety of the cavity. The core support may comprise wood or other materials. The core support provides a myriad of benefits to the post coupler ( 200 ). The male subcomponent may be made by additive manufacturing like  3 D printing. Due to such processes, the male subcomponent is more susceptible to shearing because of the plurality of layers forming the male subcomponent. With the core support disposed within the cavity, the core support can strengthen the male subcomponent and resist breakage by shear force. Other benefits of the core support include a lighter weight of the male subcomponent when the core density is less than the subcomponent density. In yet another benefit, the core support allows a fastener which fastens the male body ( 203 ) to a post via the aperture ( 222 ) to terminate at the core support instead of the more brittle male body, thereby increasing strength.
