With six(6) cute kittens (note: each cat is about 2.5cm x 2.5cm x 0.6cm ) in a set/pouch, you can stack them or place them in a row in any sequence, creating endless creative ways to play with them.In their competition to climb to the top, a careless step might cause them to fall; but don't worry, they can always try again :) Make sure your next step is secure; that's how you reach higher ground! [Collect All 5 Sets at once and Get Cheque out these ASINs: B013XTYKRS; B013YSUO1O; B013YSWERQ; B013YTC43Y; B01IH3DSDW.] [We produce the Cat Pile in a small family owned wood shop as opposed to conventional large volume wood factory.A lot of work and attention to details are put into making of the kittens, from initial wood selection to cut quality to final packaging.There are also quite a few handmade steps involved thus our production rate is not as fast, but that's how we ensure that these wooden kittens achieve consistently high quality.Thank You all Cat Lovers out there for loving our cats and supporting our small family business!]
