Catty Stacks, by Cat House System LLC, were created with the notion that there must exist a durable, eco-friendly, and aesthetically pleasing alternative to the bulky, expensive, carpet covered climbers which are often eye-sores and difficult to keep clean.

Catty Stacks offer a unique, modern design and are available in a variety of colors, making these versatile cat condos a wonderful addition to any décor. Cats LOVE boxes, and will find the interior to be roomy and easy to navigate. Cat House System LLC understands that cats love to play, so they provide accessory points which allow you to secure fun add-ons such as toys, pillows, teasers, and many new accessories that will be developed over time.

It's clear to see why cats love Catty Stacks but why should you…

STRONG - Catty Stacks are not your ordinary cardboard boxes. They are made from super-strong, heavy-weight, double-walled cardboard similar in strength to the boxes that huge, flat-screen TVs are shipped in. Boxes clip together and can be moved as a single structure and are strong and stable enough for multiple cats.

ECO-FRIENDLY - All materials are selected for their recyclable, renewable, or sustainable properties. We use highly recycled, post-consumer cardboard, 100% soy-based ink, and felt made from 100% recycled plastic bottles. Catty Stacks are light and fold flat, reducing the carbon footprint of shipping. Catty Stacks are long-lasting and can be rotated and flipped several times, ensuring you get good mileage out of every box. Once they reach their end of life, Catty Stacks can be recycled. They may even become another Catty Stack some day! : )

ECONOMICAL - Catty Stacks are less expensive than most traditional cat houses. Compared to the expensive, heavy, and bulky carpet covered wooden structures, Catty Stacks are lighter and easier to ship, and are strong enough to handle multiple cats.

CONFIGURABLE - No other cat habitat gives you so many options. From size, to shape, to colors, to accessories, Catty Stacks fit any budget and style. Cats will love how easily they can be rearrange, creating a new play area to keep them interested and stimulated, promoting good health and exercise! You can start small and add-on to Catty Stacks over time. They fit perfectly along walls or in corners.

Innovative, PATENT-PENDING design.

Catty Stack “clip-corners” allow boxes to be stacked and secured in 3 dimensions. Once secured, the whole stack can be moved together.
Perforated wall cut-outs allow you to join multiple boxes together to make roomy inside living areas, great for large or multiple cats.
Top and bottom transition holes are staggered, providing stable footing while your cat climbs up and down throughout the inside of the stacks.
Accessory points allow you to secure accessories to your stacks, such as toys, and pillows. Many new accessories will be developed over time, so please be sure to check back often.
