The Step and shelf units are covered with colour ribbed carpet and come complete with wall brackets. Shelves are perfect to attach to walls or use as extensions of cat furniture. On this shelf, cats seem like they are floating on clouds along your wall space. They enjoy lounging on strong sturdy wooden platforms covered with soft comfortable, durable carpet. Cats will always seek high vantage points – it comes from their instinct to protect themselves, and a high position for sleeping or resting gives them an aerial advantage for spotting any potential dangers around them.
