 Why your cat needs HAPPYSTACK:

  • Award winning & 5 star rated design helps fearful cats ease anxiety giving them a feeling of safety in a secure hideaway.  Happystack is great for scared, skittish, fearful or anxious cats that need a safe haven, a place where they feel confident in their own kitty home hideaway.
  • The patented pyramidal shape gives flexibility and stability for climbing and scratching every surface for one or more cats. Stack the 3 units together to form a tower or stand each unit separately. Happystacks can be used inside and outside (under a covered patio area).
  • Scratchable outside surface has durable, low pile, indoor/outdoor carpet for scratching across all levels - which makes for a happy cat and saves your walls and furniture!  PUUURFECT!  Happystack's durable design and materials also make it ideal for outdoor covered catios and decks. 
  • Easy to assemble and disassemble units with the patent pending corner hinge design. Panels are connected by a fit and slide corner hinge which helps make assembly of your cat house simple! Align the arrows and slide - that's it!  There is nothing else like it!
  • Modular & stores easy.  Stackable and nestable.  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 can be taken apart to lay flat for storage under a bed or closet.  
  • 4 floors of fun (after stacked) and 9 holes to climb and play through. Cats and kittens can climb, hide, play, sleep and scratch through the 4 levels! Your kitties could have many hours of fun and exploration with a Happystack!  
  • Multiple cats, small and large (up to 25 lbs), are supported on the units. The durable structure is made to endure constant play by one or multiple cats. 
  • Made in the USA with non-toxic materials sourced in the USA! Small business, woman owned and operated.  Easy care, wipe with lightly dampened cloth.  Safe carpet cleaning solutions may be used.
