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.

I can see how cats would find these boxes so alluring!
July 8th, 2010 at 9:54 am
Wow. What a clever idea!
Almost every cardboard box that comes into our place quickly belongs to our several cats. We’ve done various things to/with boxes, but these Catty Stacks are a simple, clever, and elegant idea.
It’s so simple, I’m embarrassed I didn’t think of it first. Heh…
We’ll be saving to get a few, and you can bet we’ll tell friends. Thanks to moderncat for bringing this idea to our attention.

These are the coolest thing I’ve seen for kitties in awhile….

July 8th, 2010 at 4:01 pm
These are awesome!
July 8th, 2010 at 4:55 pm
I love this idea and its one of the few things I’ve seen that all of my cats can play with at once.
July 8th, 2010 at 6:09 pm
These are even better than the cardboard boxes that they all can’t get enough of, especially Jules. He would even fit in one of these!
July 8th, 2010 at 6:18 pm
these are so cute. and of course all kitties love cardboard boxes!
July 8th, 2010 at 6:34 pm
wow, these are great – with a starter set of 6 I would probably only need to double that. the cats would love these.
July 8th, 2010 at 6:35 pm
I could see having to fill up a room with these boxes and perhaps even make a path through the house from one room to another so that they cats would have their own private walkway. they would/could have a world of fun. this is definitely something that would be put to good use in my house.
July 8th, 2010 at 7:29 pm
Great idea! I know 4 kitties who would LOVE these!
July 8th, 2010 at 8:09 pm
Sweet! Those are so AWESOME. If I don’t win I might buy some anyways for my three cats. I was just thinking of a way to create a play area for them.
July 8th, 2010 at 9:07 pm
Looks like an expensive version of Cube. (www.TheCreativePet.com)
July 8th, 2010 at 9:17 pm
Wow,
my little troublesome kitty would love this!
She hides in absolutly everything from tiny boxes to her own play tunnel
Think this would be her dream come true!
July 8th, 2010 at 9:35 pm
Oh my gosh, these would be perfect for my kitty Cortana. They could be place next to a window for ultimate bird watching!
July 8th, 2010 at 10:28 pm
