Our mission is to design not only the most innovative cat furniture on the market, but the highest quality too. Unlike most other cat furniture, our cat towers are made out of hardwood (rubberwood). In addition to its excellent furniture making characteristics, rubberwood is considered to be a green product because it is not harvested until its latex producing days have past. Rubberwood, along with natural Sisal scratching surfaces and EverStrand Carpet (100% Post-Consumer Carpet Made From Recycled Plastic Bottles) make our towers the greenest cat furniture too!
