how to diy a cat house

If you want to know how to diy a cat house, you can build a simple, comfortable shelter with inexpensive materials and basic tools. The easiest design is a small enclosed box with a doorway, insulation or padding, a waterproof outer layer if it will be used outdoors, and a removable or washable sleeping surface.

The best design depends on whether the house will be used indoors or outside. An indoor cat house can focus on comfort and appearance, while an outdoor shelter needs to protect the cat from rain, wind, moisture, and temperature changes.

Choose the Right Design

Before cutting materials, decide where the cat house will be used.

For an indoor cat house, you can use cardboard, plywood, foam board, fabric, or other lightweight materials. The shelter mainly needs to provide a quiet place where the cat can sleep or hide.

For an outdoor cat house, use sturdier materials and concentrate on keeping the interior dry and protected from wind. A simple plastic storage container can also be converted into a basic shelter, provided it is large enough and has a suitable entrance.

For outdoor community or feral cats, a shelter should provide protection without creating a situation where the cat could become trapped.

Materials You Can Use

A simple DIY cat house doesn’t require expensive materials.

For an indoor version, you might need:

• A sturdy cardboard box or plywood
• A ruler or measuring tape
• Pencil
• Utility knife or saw
• Non-toxic adhesive
• Fabric or a washable blanket
• Sandpaper if using wood

For an outdoor version, consider:

• Exterior-grade plywood or a suitable weather-resistant container
• Insulation material
• Waterproof roofing material
• Screws
• Outdoor-safe sealant
• A washable sleeping pad
• A raised base or platform

Avoid materials that can easily splinter, expose sharp edges, or contain loose pieces that a cat could chew and swallow.

Measure the Cat House

The shelter should be large enough for your cat to enter, turn around, lie down, and change positions comfortably.

At the same time, avoid making an outdoor shelter unnecessarily large. A smaller enclosed space can be easier for a cat to warm with its own body heat.

Measure your cat before deciding on the dimensions. If you’re building for multiple cats, allow enough room for the cats that will actually use the shelter.

The entrance should also be large enough for the cat to pass through comfortably. Don’t make it unnecessarily large if the shelter is intended for cold-weather outdoor use because a large opening allows more wind and weather inside.

Build a Simple Cardboard Cat House

Cardboard is one of the easiest materials for an indoor DIY cat house.

Step 1: Find a Strong Box

Choose a clean, sturdy cardboard box that’s large enough for your cat to comfortably enter and lie down.

Remove staples, loose tape, and anything that could become a hazard.

Step 2: Mark the Entrance

Use a ruler and pencil to mark an entrance on one side.

A rounded or slightly arched opening can work well. Cut carefully with a utility knife and keep the opening smooth.

Don’t leave sharp cardboard edges or exposed staples around the entrance.

Step 3: Reinforce the Structure

Use additional cardboard panels inside the walls if the box feels weak.

You can also create a second layer around the outside to make the shelter more rigid.

Step 4: Add a Comfortable Floor

Place a washable blanket, towel, or cat bed inside.

Make sure the bedding doesn’t block the entrance or create a tripping or entanglement hazard.

Step 5: Add a Roof

The existing box flaps can often be folded into a simple roof. If you want a more decorative design, cut additional cardboard pieces and attach them securely.

You can also create a cardboard cat house shaped like a small cabin, castle, or covered bed.

Build a Wooden Cat House

Plywood can create a much more durable cat house, especially for outdoor use.

A basic wooden design consists of:

1. A floor
2. Four walls
3. A roof
4. One entrance

Cut the panels to your planned dimensions and sand every exposed edge before assembly.

Use screws appropriate for the material rather than leaving sharp screw points inside the shelter.

If you plan to paint or seal the wood, choose products suitable for the intended environment and allow everything to cure and dry completely before the cat uses the house.

Add Insulation for an Outdoor Cat House

Insulation can make a significant difference in an outdoor shelter.

You can place insulation between the outer and inner walls of a wooden shelter, provided it is fully enclosed and inaccessible to the cat.

Don’t leave loose insulation exposed inside the sleeping area. Cats can scratch, chew, or pull apart materials that aren’t properly enclosed.

The goal is to create a barrier that slows heat loss while keeping the sleeping area safe and dry.

Make the Roof Weather Resistant

Outdoor cat houses need protection from rain and moisture.

A simple pitched roof can help water run away from the shelter rather than collecting on top.

You can add a weather-resistant roofing layer over the plywood. Make sure the roofing material is securely attached and that there are no sharp exposed edges.

The roof should also extend slightly beyond the walls where practical, helping reduce rain entering through the doorway.

Raise the House Off the Ground

For an outdoor cat shelter, placing the house directly on wet or cold ground can reduce its effectiveness.

A raised platform can help keep the floor away from moisture and improve airflow underneath.

The platform must be stable and strong enough to support the shelter and any cats using it.

If you’re placing the shelter outdoors, choose a location that is naturally protected from prevailing wind and heavy rain.

Choose the Right Bedding

For an indoor cat house, a washable blanket or cat bed can work well.

For outdoor shelters, bedding needs more consideration because some materials can absorb moisture and become cold when wet. In many outdoor-community-cat shelter designs, straw is preferred because it resists moisture better than materials such as blankets or towels.

Whatever material you choose, check it regularly and replace it if it becomes wet, dirty, moldy, or damaged.

Make the Entrance Safe

The entrance is one of the most important parts of the design.

It should:

• Be large enough for the cat
• Have smooth edges
• Allow easy entry and exit
• Avoid sharp materials
• Keep unnecessary drafts out
• Not create a trap

For an outdoor shelter, you can position the entrance away from the direction of prevailing wind when possible.

Some shelters use a short entrance tunnel or offset doorway to reduce direct wind exposure.

Add a Second Exit for Outdoor Cats

A second opening can sometimes be useful in an outdoor shelter, particularly for cats that need an escape route from other animals.

If you add a second entrance, make sure both openings are easy to use and aren’t positioned in a way that allows rain to enter easily.

For a single indoor cat, a second opening isn’t always necessary.

Keep the Cat House Dry

Moisture can make an outdoor shelter much less comfortable.

Check the house regularly for:

• Roof leaks
• Wet bedding
• Condensation
• Damaged walls
• Water pooling underneath
• Mold
• Chewed or damaged materials

A DIY shelter may look waterproof when first built but develop leaks after exposure to rain and weather.

Make It Easy to Clean

A cat house should be designed so you can inspect and clean the interior.

A removable roof or hinged access panel can make maintenance easier, particularly with a wooden shelter.

Avoid creating inaccessible spaces where urine, feces, food, or moisture can accumulate.

For an indoor house, washable covers make regular cleaning much easier.

Avoid Common DIY Mistakes

One of the easiest mistakes is making the house too large. A huge shelter may be comfortable but can be less effective at retaining warmth outdoors.

Another mistake is leaving insulation, adhesive, staples, screws, or sharp edges accessible to the cat.

Other problems include:

• Using untreated cardboard outdoors
• Creating a roof that leaks
• Using bedding that stays wet
• Making the entrance too small
• Making the shelter unstable
• Using unsafe electrical heating equipment
• Painting or sealing surfaces before products have fully cured

If you’re unsure whether a material is appropriate for animals, choose a simpler, safer alternative.

Can You Make a Cat House From a Plastic Storage Bin?

Yes. A sturdy plastic storage container can be converted into a basic outdoor shelter by cutting an appropriately sized entrance and adding suitable bedding.

The container should be large enough for the cat and positioned securely so it cannot easily tip over.

Any cut plastic edges must be smoothed and protected so they cannot injure the cat.

For outdoor use, the shelter should also be positioned somewhere protected from rain and direct wind.

How to Make a DIY Cat House More Comfortable

Once the basic structure is complete, you can make it more appealing without compromising safety.

Try adding:

• A comfortable sleeping pad
• A washable interior liner
• A scratching surface nearby
• A small toy
• A raised platform
• A covered entrance
• A familiar-smelling blanket for an indoor cat

Don’t overcrowd the sleeping area. Cats need enough room to turn around and settle comfortably.

Frequently Asked Questions

What is the easiest way to DIY a cat house?

A sturdy cardboard box is probably the simplest indoor option. Cut a safe entrance, reinforce the structure, and add comfortable bedding. For outdoor use, a weather-resistant plastic container or properly constructed wooden shelter is more suitable.

What is the best material for an outdoor DIY cat house?

Weather-resistant wood or a sturdy plastic container can work well. The design should also include appropriate insulation, moisture protection, and a secure roof.

How big should a DIY cat house be?

It should be large enough for the cat to enter, turn around, lie down, and change positions comfortably. Avoid making an outdoor shelter unnecessarily large because a more compact space can be easier to keep warm.

Can I use cardboard for an outdoor cat house?

Cardboard is generally better suited to indoor use because it absorbs moisture and can quickly deteriorate when exposed to rain. For outdoor shelters, use a weather-resistant structure instead.

What should I put inside an outdoor cat house?

The bedding should remain dry and provide a comfortable resting surface. Straw is commonly used in outdoor community-cat shelters because it resists moisture better than many fabrics. Check the shelter regularly and replace wet or contaminated bedding.

Should a DIY cat house have two entrances?

Not necessarily for an indoor cat. For an outdoor or community cat shelter, a second exit can provide an escape route if another animal enters. The openings should remain safe and accessible.

Conclusion

Learning how to diy a cat house can be as simple as modifying a cardboard box for indoor use or building an insulated wooden shelter for outdoor cats. The most important considerations are size, safety, comfort, weather protection, and easy maintenance.

For indoor cats, focus on a cozy, stable space with comfortable bedding and a safe entrance. For outdoor cats, prioritize a dry, insulated and weather-resistant shelter that protects against wind and precipitation.

You don’t need an elaborate design to give a cat a useful shelter. A simple structure built from appropriate materials can provide a comfortable place to rest as long as it is stable, safe, dry, and suited to the environment.
