Our mission is to provide quality products that your cat will love! Your kitties could have many hours of fun and exploration with a Happystack! Our Happystack® products include different shapes (Square and Hexagon), colors, patterns, and a couple different doorway sizes to ensure that you have plenty of options for your cat.

Your cat(s) will love HAPPYSTACK!  Why your cat(s) need a Happystack Hexagon:

-- The Hexagon design is wider than the Square design and has more floor space for your cat(s) to play, climb, hide, sleep, and lounge!  This Happystack has a very modern design with a trellis pattern to add to your home décor! 

-- The patented pyramidal shape of the Happystack gives flexibility and stability for climbing and scratching of every surface by one or more kitties. Stack units together or stand separately.  Cats and kittens can climb, hide, play, and scratch through four levels or sleep in any level! 

-- Happystacks offer fun at many levels with 4 floors (after stacked) and 9 holes to climb and play through.  Outside surface has carpet for scratching across all levels - thick scratching posts all over which makes for a happy cat and saves your walls and furniture!  PUUURFECT!

-- Our fit and slide corner hinge helps make assembly of your cat house easier and has a patent pending! Align the arrows and slide - that's it!  There is nothing else like it! 

-- Happystacks can support small or large cats (up to 25 lbs), are durable, and are made to endure constant play by one or multiple cats.  Happystacks can be used inside and outside (only under a covered patio or area).  Our products are made in the USA with materials sourced in the USA!  

-- Our award winning design helps fearful cats decrease anxiety by giving them a feeling of safety in a secure hideaway.  Happystack is great for scared, skittish, afraid or anxious cats that need a safe haven, a place where they feel confident in their own kitty home hideaway. Happystacks were originally developed for cats who hide under a bed or in a room - shy cats need a safe place like Happystack. 

Add this modern cat house to your home décor! Made in the USA! Easy to assemble and disassemble.  Units can be nested together by placing smaller units inside larger unit, creating a storable basket which is lightweight for ease of transportation. The panels are connected using a corner hinge that can be taken apart to allow units to lay flat for storage.
