XXL Cat Tree with Enclosed House – The Citadel

The Citadel is one of our largest and best-selling XXL cat trees, combining the privacy of a spacious enclosed cat house with the climbing space of a premium multi-level cat tower. Handcrafted in the USA from solid wood, this heavy-duty cat condo is built for everything from playful kittens to Maine Coons, Ragdolls, and other extra-large cats.

Designed for multi-cat households, The Citadel features oversized lounging platforms, a spacious enclosed cat condo, and exceptional stability that gives every cat their own place to climb, scratch, lounge, and rest. Available in sophisticated Black & Gray or Black & Beige finishes, this luxury cat tower blends beautifully into modern homes while providing the durability serious cat owners expect.

For even greater longevity, The Citadel is now available with an optional natural sisal rope scratching post upgrade. 

Handcrafted Quality – Made in the USA

Built to Last with Solid Wood, Premium Carpet & Upgraded Scratching Options

Every Citadel is handcrafted in the USA using solid wood, thick household-grade carpet, and durable scratching surfaces designed for years of daily use. Unlike imported particle-board cat trees, The Citadel delivers exceptional stability, long-term durability, and premium craftsmanship that stands up to even the largest cats.

For customers who prefer natural scratching surfaces, The Citadel is also available with an optional sisal rope scratching post upgrade, offering a premium scratching experience while extending the life of your investment.

Superior Craftsmanship and Safe, Non-Toxic Materials

Our builders use only pet-safe materials and thick carpet for maximum traction and durability, ensuring a safe climbing environment for every cat.

Spacious Multi-Level Design for Active Cats

Tall, Spacious & Built for Every Cat in the Home

A Standing at 75 inches tall with oversized lounging areas, The Cit5adel creates valuable territory for cats of every size.  Whether you have energetic kittens, adult cats, senior cats, Maine Coons, Ragdolls, or multiple large breeds living together, every level provides comfortable space for climbing, stretching and relaxing.

Ideal for Multi-Cat Homes

Multiple oversized platforms, elevated resting areas, and the spacious enclosed cat condo give every cat their own territory. This helps reduce competition while encouraging healthy climbing, observation, play, and quiet retreat—all within one premium cat tower.

Private Enclosed Cat House for Security & Comfort

Cozy Hideaway Condo for Rest and Retreat

Unlike many cat trees that only offer open perches, The Citadel includes a spacious enclosed cat condo positioned high above the floor. This elevated cat house creates a warm, secure retreat where cats can nap, observe the room, or simply enjoy quiet time away from the activity below.

Large breeds like Maine Coons and Ragdolls often prefer enclosed resting spaces that provide warmth and security. The generously sized condo area offers enough room for bigger cats while maintaining the stability and structural integrity The Citadel is known for.

Ideal for Multi-Cat Homes That Need Territory Separation

In multi-cat households, vertical space alone is not enough — cats also need private zones. The enclosed condo helps reduce tension by giving one cat a dedicated retreat space while others use the upper platforms.

This combination of open perches and a built-in cat house makes The Citadel both a climbing tower and a secure resting environment.

Upgrade to Additional Sisal Rope Scratching Posts

One of the newest features available for The Citadel is the option to upgrade from carpet-covered scratching posts to natural sisal rope scratching posts.

Unlike many cat trees that eventually require complete replacement, The Citadel has been designed with long-term ownership in mind. When your sisal scratching posts eventually wear from years of use, certain replacement scratching posts can be purchased separately, allowing you to renew your favorite cat tree without replacing the entire structure.

Benefits of upgrading include:

• Natural sisal provides an outstanding scratching surface that many cats prefer.

• Helps satisfy natural scratching instincts while protecting household furniture.

• Extend the useful life of your investment.

• Replace certain scratching posts in the future could save you money.

It's one more reason why The Citadel continues to be one of our most innovative and best-selling cat towers.

Comfort Meets Function – Real Carpet and Cozy Perches

Plush Carpet for Ultimate Comfort

The thick household-grade carpet provides exceptional traction for climbing while creating warm, comfortable resting areas throughout the tower. Customers who prefer natural scratching surfaces also have the option of upgrading to premium sisal rope scratching posts for even greater scratching satisfaction.

Easy to Maintain and Long-Lasting

Our durable carpet and solid-wood base mean this cat tree withstands years of scratching, climbing, and lounging without losing its appeal.

Modern Furniture Styling for Today's Homes

Large cat furniture doesn't have to dominate your living room.

The Citadel is available in two attractive two-tone color combinations—Black & Gray and Black & Beige—that complement both modern and traditional interiors. The clean lines, premium materials, and furniture-inspired appearance make it a beautiful addition to your home while giving your cats a luxurious place to climb, scratch, and relax.

It's a cat tree built for your cats without sacrificing the style of your home.

The Perfect Cat Tree for Maine Coons, Ragdolls & Large Breeds

Big cats need furniture built to their scale. The Citadel is engineered for weight and balance — no flimsy bases or thin platforms. Its extra-wide perches, solid wood supports, and heavy-duty construction provide the perfect environment for extra-large breeds.

Why The Citadel Is an Ideal Large Cat Tree for Big & Maine Coon Cats

The Citadel was designed specifically for large cats and multi-cat households that need more than a standard cat tree. Built with solid wood construction and a heavy-duty base, this large cat tree delivers the strength and stability required for Maine Coon cats, big breeds, and heavier adult cats that can overwhelm lightweight alternatives.

With its tall profile and wide lounging platforms, The Citadel allows large cats to climb, stretch, and relax comfortably without wobbling or flexing. Every level is engineered to support substantial weight, making this a dependable heavy-duty cat tree for active or multi-cat homes.

Like all of our products, The Citadel is handcrafted in the USA using durable materials designed for long-term use. If you’re looking for a premium large cat tree that prioritizes stability, size, and craftsmanship, The Citadel stands in a class of its own.

A Luxury Cat Tower Built to Last for Years

Whether you're furnishing your first multi-cat home or upgrading from a lightweight imported cat tree, The Citadel delivers the stability, craftsmanship, and timeless design that have made it one of our flagship products.
