<p>The invention provides a barrier unit (50) which includes a plurality of elongate transversely spaced interconnected barrier elements (14) arranged in a grid. The barrier elements each have a longitudinal axis which extends generally perpendicular to the plane of the grid, the axes of the barrier elements (14) being parallel. Adjacent barrier elements (14) are connected together adjacent their lower ends by means of bridge elements. Connecting elements (56) are connected to the barrier elements (14) and are receivable over barrier elements of another barrier unit to connect the barrier units together. The barrier units are used to form a barrier for animals, particularly domestic animals such as cats and dogs, the upper ends of the barrier elements (14) forming an uneven surface over which the animal must walk in order to gain access to a particular area. The configuration of the barrier elements (14) is such that it makes it uncomfortable for an animal to walk thereon thereby serving as a deterrent.</p> |
