Cats love boxes, that is the universal truth. Amsterdam based company Poopy Cat embraced the idea, initially by creating their hit cardboard litter box, and now with the new line of cat playware. BLOCKS is a successfully funded Kickstarter project that goes into production in March. The principle is simple and brilliant: the BLOCKS package consists of two beams, two cubes, tunnel, bridge, slide and two types of connectors. It is light yet sturdy and can withstand any cat. The modularity of the design allows you to adjust it to your space constraints and your cat’s preferences. The boxes are made from recycled and biodegradable cardboard, easy on the wallet and the environment alike.
