A cat house is more than just a cozy corner—it’s a space where cats feel secure, stimulated, and truly at home. Whether you’re crafting a DIY project or browsing for a store-bought model, the right cat house should match your living space, your cat’s personality, and your functional needs. This guide explores 25+ cat house ideas suitable for indoors, outdoors, small apartments, and multi-pet homes.

From space-saving solutions to design-forward furniture, this article breaks down popular styles, materials, and placement tips to help you choose or create a cat house that both you and your cat will love.

Why Cat Houses Matter

Cats are territorial, solitary creatures by nature. They often seek enclosed spaces to nap, hide, or observe their surroundings without being disturbed. A well-designed cat house offers physical comfort and psychological security. It can also reduce unwanted behaviors like hiding in closets or scratching furniture.

Cat houses also help define boundaries in homes with multiple pets, offering individual safe zones that reduce stress and conflict.

Indoor Cat House Ideas

Modern Wooden Cat Houses

Sleek wooden enclosures with minimalist design fit well in Scandinavian or Japandi-style homes. Many double as end tables or nightstands, combining form and function.

Felt or Wool Dome Houses

Made from soft, breathable materials, these cocoon-style houses provide warmth and sound insulation. They’re especially popular on Pinterest for their aesthetic and texture.

Multi-Level Cat Condos

These combine several functions—hiding spots, perches, and scratching surfaces. Perfect for active cats or multi-cat households, especially in apartments.

Under-Furniture Enclosures

Think litter-box furniture, TV stands with pet compartments, or storage benches with hideaways. These utilize unused space and keep your home looking clean and organized.

Upcycled Suitcase or Basket Houses

Vintage suitcases or large wicker baskets converted into cat homes are trending among DIY enthusiasts. Add padding and a curtain for comfort and privacy.

Tent-Style Fabric Cat Houses

Lightweight, collapsible, and easy to clean. These are ideal for renters or those with limited space who want a portable option.

Outdoor Cat House Ideas

Insulated Weatherproof Shelters

For cats who spend time outdoors, especially in cooler climates, insulation is critical. Look for double-walled plastic, foam-lined interiors, and waterproof construction.

Elevated Wooden Cabins

Small wooden shelters on legs help keep moisture out and provide a rustic look. These are common in backyards or on porches.

Catios with Built-In Shelters

Combining a screened outdoor enclosure with enclosed sleeping quarters offers protection from predators while allowing fresh air and stimulation.

Recycled Plastic Barrel Houses

Upcycled barrels or containers converted into shelters with added insulation are low-cost and durable solutions for semi-feral or outdoor cats.

Covered Patio Nooks

If you have a patio or balcony, a small covered area with a weatherproof mat and bedding can become a beloved sunbathing and nap spot.

Cat House Ideas with Additional Functionality

Litter Box Enclosure Cat Houses

These serve a dual purpose—concealing litter boxes while also offering your cat a hiding spot. Many are designed to match home décor.

Cat House with Scratching Post

Combining a cat house with a built-in scratching surface satisfies both comfort and behavioral needs, saving space and protecting furniture.

Heated Cat Houses

Especially useful in colder regions or for aging cats with arthritis, heated pads or electric warming elements provide year-round comfort.

Window-View Cat Houses

Designed with an open front or low windows so your cat can lounge while observing the outdoors. These can be placed on window sills or next to large glass doors.

DIY Cat House Concepts

Cardboard Box Builds

The simplest option. Cut doors and windows, tape securely, and decorate. Ideal for short-term use, especially when space or budget is tight.

IKEA Hacks

Repurposing small IKEA units (like the KALLAX or BESTÅ series) with added fabric, foam, or wooden doors can create custom cat nooks.

Pallet Wood Cat Houses

Pallets are inexpensive and sturdy. Sand, paint, and assemble them into compact cabins or stackable units. Great for rustic or boho aesthetics.

Repurposed Furniture

Turn an old cabinet, drawer, or side table into a stylish cat house by removing internal shelves, cutting entry points, and adding padding.

Choosing the Right Cat House

Size and Entryway

Your cat should be able to comfortably turn around and stand inside. Entry points should be wide enough to avoid trapping heat but small enough to offer a sense of security.

Ventilation

Look for houses with open fronts, mesh sides, or airflow holes to prevent overheating—especially in enclosed designs.

Easy Cleaning

Removable cushions, wipeable interiors, and lightweight builds make regular cleaning much easier, especially if the house doubles as a litter enclosure.

Materials

Choose non-toxic, durable materials. Avoid treated woods for DIY houses unless sealed safely. Felt, solid wood, and washable fabrics are ideal.

Aesthetics

Since many cat houses are part of your living space, choose colors and materials that align with your interior design. Neutral tones, wood textures, and soft fabric finishes are most versatile.

Placement Tips for Maximum Use

  • Avoid placing cat houses in noisy or high-traffic areas. Cats prefer quiet, semi-private locations.
  • If placing near windows, ensure limited direct sun during hot hours.
  • In multi-cat homes, offer multiple houses in separate zones to reduce territorial disputes.
  • Elevated placement can make your cat feel safer, especially if you live with dogs or toddlers.
