• Have a cat, bunny, or small dog? I highly recommend buying a few of these stackable cardboard cubes and bridges from Cat Amazing.
• Cat Amazing’s Catty Stacks kits and are affordable, easy to assemble, and surprisingly durable. They’ve held up impressively well since we bought them one year ago. 
• My partner and I dubbed our setup “Box City.” Of the many designated (and some undesignated) nap spots in our apartment, this customized cat condo is definitely our cat’s favorite place to nap and play. 

Our cat Lady’s favorite cat toys and cat beds aren’t the ones we bought specifically for her. That’d be very un-catlike. No, they’re things like tissue paper, headphone wires, and the cardboard boxes her autoshipped pet supplies from Chewy arrive in each month. Give Lady a box, any box, and she’ll sit in it, sleep in it, and play in it until my partner or I finally decide it’s time to recycle it. 

We had a big cardboard-box problem until about one year ago. That’s when we discovered Catty Stacks are all cat owners need to solve the problem of having unsightly boxes strewn all over their home. 

Catty Stacks are cute, stackable cubes and bridges that are affordable, easy to assemble, and surprisingly durable. They are made of corrugated cardboard and come in four colors — Snow White, Chocolate Brown, Pistachio Green, and Giraffe Print — that are meant to be mixed and matched to build a customized cat condo. Our setup comprises two Giraffe Print cubes and two Pistachio Green cubes, but you can stack to your heart’s content (some cat owners get really creative!).

Each Catty Stacks kit costs $30 and includes, two cubes, one bridge, eight connecting clips, and assembly instructions. Assembly took us less than 10 minutes for each kit; the written-out instructions are straightforward (there are also video instructions) and the cubes come with pre-perforated punch-out walls on all eight sides.

If you have a larger cat, you can expand the openings on your cubes to better accommodate them. We didn't need to widen the openings on our Catty Stacks since Lady is very petite at less than 10 pounds. If you do want to, Cat Amazing, the manufacturer of Catty Stacks, recommends cutting the perforations first and then pushing them out since they're meant to withstand the full weight of a cat.

Like other cat complexes and cat trees we recommend, Catty Stacks are designed to keep indoor cats entertained and active, allowing them to climb, perch, lounge, and play. Nearly 70% of Amazon customers who've bought Catty Stacks give them a five-star rating, and Lady gives "Box City" two paws up.  

If you're unsure of how much your cat will like these boxes, I recommend starting with just one two-pack and adding to your setup over time.
