Most cat furniture consists of wooden posts with carpeting wrapped around it. While serviceable, you might want to create something larger at less cost, and that’s where Katris comes in.

The Tetris-style pieces fit together to provide a variety of levels for your cat to climb on while also making nooks and crannies where you can store your books, or they can be used as a table.

Made of 100-percent recyclable corrugated fiberboards and SGS-certified non-toxic glue, the shapes each weigh between 6.5 and 8.6 pounds a piece. You make a base, and then choose which shapes best fit your place and your cat’s predilections. Use a clip to fasten the different shapes together, and you have a table, bookshelf, or shoe rack that cat is meant to destroy. Each shape costs about $50, so that may be an expensive toy for your cat, but since most cat lovers serve their cat as their superiors anyway, Katris might be a way to keep your cat happy while lightening your wallet at the same time.
