A fence post for an animal enclosure including a first member, a second member, a collar, and a fastener. The first member and second member are substantially the same length. The second member has a cross-bore at a proximal end thereof, the collar defines an aperture, and the first member is fixedly attachable to the collar. The second member is configured to be partially received within the collar for alignment of the cross-bore and the aperture, and the second member is fixable relative to the collar by means of the fastener arranged to at least partially passthrough said cross-bore and said aperture.
