A cat scratching post that includes a plurality of supports between which an outer covering is disposed. The supports are coupled with at least one joint that can comprise a spline that can be ribbed and that can form part of an end cap. In another preferred embodiment, the supports engage each other and form a post assembly that can be hollow. One preferred joint comprises a tongue and groove coupling. One preferred coupling includes a snap received in a receiver. One preferred post assembly is formed of a pair of supports of substantially identical construction. Each support preferably comprises a spar formed from a common extrusion producing spars of substantially identical cross-section. In assembly, one of the spars is reversed relative to the other so they mirror one another before being engaged to one another using a plurality of spaced apart joints integrally formed of the spars.
