Here’s a fun new product that lets you create a customized climbing structure for your cats. It’s the Catty Stacks, designer cat house system. These super strong corrugated cardboard boxes can be connected in three dimensions to create all sorts of configurations for climbing, perching, playing, napping, and hiding. The nice folks at Catty Stacks sent us a set to test out and they were an instant hit. Here are Simba and Dee checking out the new play station:

The boxes ship flat and are really easy to set-up, just unfold and insert some tabs into slots and you’re ready to go. The special corner design allows you to clip the boxes together (clips are included) to create a nice sturdy structure. Once the boxes are clipped together, you can lift the whole stack to move it (just make sure there aren’t any cats inside!)

Holes on the side of the boxes allow kitties to enter and exit and connect from one box to the next. When two boxes are clipped together, you can remove a larger portion of the side panel to create a more spacious inner lounge area. When boxes are stacked on top of each other, the vertical access holes are staggered, making it easy for kitty to get her footing as she climbs up through the boxes. The thing I’m most impressed with is the strength of the double thickness cardboard. This is some of the strongest cardboard I’ve seen, so the Catty Stacks should last a long time.

There are a number of accessories you can purchase as add-ons for your Catty Stacks, including a crawl tube that connects between two boxes, special felt pillows for extra comfort, and an animation wand that connects easily to one of the accessory points and has a clip on the end to attach kitty’s favorite toy. Here’s Theo getting ready to attack the dangling toy:

The boxes come in light pink, chocolate brown, sky blue, pistachio green, and white, all printed with 100% soy-based inks. The cardboard used is also 100% recycled and recyclable. You can choose any combination of colors when ordering the boxes in kits ranging from one box for $17.99 US, to ten boxes for $129.99 US.

Cool. New perches and hiding spots for kitty.
Thanks for the giveaway!!
July 5th, 2010 at 9:18 am
I’m pretty sure my Clementine would mess the thing in no time, but she would have fun anyhow combining her two favorite activities : climbing and shredding!
July 5th, 2010 at 9:18 am
I absolutely love it!
Thanks for being such a great resource
July 5th, 2010 at 9:19 am
Like many of the other comments have said, my cats also already adore cardboard so these boxes are a definite design ‘yes.’
July 5th, 2010 at 9:19 am
So cool, I’ll even pay the shipping for my country…
July 5th, 2010 at 9:19 am
Looks fun!
July 5th, 2010 at 9:19 am
Cleo would be “KING of the World” with a set of stacks of her very own. Maybe she’d stay off the entertainment center too.
July 5th, 2010 at 9:19 am
These boxes are awsome! My cats would love them! Hope I win!
July 5th, 2010 at 9:19 am
My kitties would love that!
July 5th, 2010 at 9:19 am
Very neat – easy to move around!
July 5th, 2010 at 9:20 am
Mine all love boxes so I know that they would enjoy these.
July 5th, 2010 at 9:20 am
OMG WAAAANT! These are so cool!
July 5th, 2010 at 9:20 am
oh how wonderful! would work great as a playground in our screen porch (aka the cat zone) for our three kitties!
July 5th, 2010 at 9:20 am
Wow!It looks fun!
July 5th, 2010 at 9:20 am
That is genius! I would love to win these, all my guys have is a sad looking carpet house.
July 5th, 2010 at 9:20 am
such a cool idea ^_^ very clever
July 5th, 2010 at 9:21 am
Looks like a lot of fun (even though I am not (yet) a cat)!
July 5th, 2010 at 9:21 am
this is awesome! i appreciate the “customizability”.
July 5th, 2010 at 9:21 am
My kitty kiki would love this! I just moved into a new apartment, and kiki needs some new furniture too.
July 5th, 2010 at 9:22 am
How fun! My kitties would love it!
July 5th, 2010 at 9:22 am
How fun and love the colors too!
July 5th, 2010 at 9:22 am
So fun! My cat loves cardboard boxes as-is, so she’d love these even more!
July 5th, 2010 at 9:22 am
this is a great product … I would love some people-sized ones too! My foldies would be in 7th heaven!!
July 5th, 2010 at 9:22 am
Wow. That. is. AWESOME. My cat would go nuts. He loves boxes.
July 5th, 2010 at 9:22 am
those look so great. eco-friendly, cool colors and lightweight what more could you ask for. my cat would love them!
July 5th, 2010 at 9:22 am
LOVE these – wonder if it would hold up to a cat of 18+ lb??
July 5th, 2010 at 9:22 am
Cardboard is the preferred material for all things associated with cats in our house. And the Cardboard Climber looks way better than the assortment of boxes left by the UPS man. These are sure to be a hit in our house!
July 5th, 2010 at 9:22 am
Oh wow, this is EXACTLY what I’ve been looking for. My kitty and I are moving to the Caribbean for 2 years and I’m having a hard time figuring out how I’m going to ship all of her cat toys. These are perfect for travel and look like soooo much fun!
July 5th, 2010 at 9:23 am
climb climb climb
July 5th, 2010 at 9:23 am
My girls would love these!
July 5th, 2010 at 9:23 am
My cat would love this!! What a great idea!
July 5th, 2010 at 9:23 am
We have tried making our own version of this and I think we just fail with scissors, cardboard, and tape……..but our cats would go APE for these
July 5th, 2010 at 9:23 am
Adorable! All my cats would love the catty stacks!!
July 5th, 2010 at 9:23 am
It would be good to encourage them to climb on things other than my nic-nac shelf
July 5th, 2010 at 9:23 am
This is such a cute idea. I remember building a cardboard box playground for my kitties years ago, using lots of duct tape and string. It didn’t last long, but they sure did have a blast with it. I’d definitely love to win this, and my six kitties would have an absolute blast playing with it.
July 5th, 2010 at 9:23 am
What a great idea… my kitties would love a set!
July 5th, 2010 at 9:23 am
Cool idea! My cats love boxes anyways!
July 5th, 2010 at 9:23 am
I think this is brilliant. What’s not to like?
July 5th, 2010 at 9:24 am
Fab idea! Good for scratching to.
July 5th, 2010 at 9:24 am
Cool! I don’t know where I’d put them, but considering there’s always space for a cardboard box or two for my cat to play in, I’m sure we’d come up with something. He looooooves boxes, so as long as these are big enough for a big cat (around 18 pounds) I’m sure he’d love them.
July 5th, 2010 at 9:24 am
My guys, Noodles and Meep, LOVE to hide in cardboard boxes…so this would be great for them!
July 5th, 2010 at 9:24 am
Our little Babe loves cardboard boxes. So these would be right down her alley!
July 5th, 2010 at 9:24 am
Such a wonderful romper room for kitties!!!
