Building a safe, warm, and dry shelter for outdoor or community cats is a straightforward and rewarding project that provides essential protection from the elements.
Outdoor and feral cats face harsh weather conditions year-round, from bitter cold and snow to sweltering heat and rain. A well-constructed shelter can significantly improve their quality of life, offering refuge and a secure space. These shelters are often made from repurposed materials, making them an affordable and impactful way to support feline welfare in your community.
Materials You'll Need
To construct a basic, effective cat shelter from a plastic bin, gather the following:
- Plastic Storage Bin: A sturdy, waterproof bin with a lid, ideally 18-gallon to 30-gallon, which is suitable for one or two cats.
- Insulation Material:
- Styrofoam insulation boards (1-2 inches thick) or
- Reflective insulation (e.g., rigid foam board with foil facing)
- Bedding: Clean, dry straw (NOT hay, as hay absorbs moisture and can mold).
- Cutting Tools:
- Utility knife or box cutter (for insulation)
- Jab saw or Dremel tool (for cutting the bin's entrance)
- Adhesive/Tape:
- Gorilla tape (or heavy-duty duct tape) for sealing edges.
- Optional: Spray foam adhesive for securing insulation.
- Measuring Tools: Marker and measuring tape.
- Elevation (Optional but Recommended): Bricks, wooden pallets, or waterproof cinder blocks.
Step-by-Step Guide to Building a Cat Shelter
Follow these steps to construct a durable and insulated shelter for cats:
1. Choose Your Container
Select a robust plastic storage bin. Totes ranging from 18 to 30 gallons are typically ideal for one or two cats, as they provide enough space while allowing body heat to effectively warm the interior. Ensure the lid fits securely.
2. Create the Entrance
The entrance needs to be large enough for a cat but small enough to deter larger predators and conserve heat.
- Measure and Mark: On one of the shorter sides of the plastic storage bin, measure and mark a 5-inch square. Position this opening at least 3 inches from the bottom of the bin. This specific 5-inch square allows cats to comfortably pass through while being small enough to prevent larger wildlife (like raccoons or opossums) from easily entering.
- Cut the Opening: Carefully cut out the marked square using a jab saw or a Dremel tool.
- Smooth the Edges: After cutting, inspect the edges of the opening. If they feel rough or sharp, cover them thoroughly with Gorilla tape to create a smooth, safe finish and prevent injury to the cats.
3. Insulate the Shelter
Proper insulation is critical for keeping the shelter warm in winter and cool in summer.
- Cut Insulation: Cut pieces of Styrofoam insulation board to fit snugly against all four interior walls, the bottom, and the lid of the storage bin.
- Install Insulation: You can secure the insulation pieces using spray foam adhesive or simply cut them to fit very tightly within the bin, creating an insulated "box within a box." For enhanced thermal performance, consider lining the interior walls of the plastic bin with reflective insulation before adding the Styrofoam.
4. Add Bedding
The right bedding provides warmth and comfort.
- Use Straw: Fill the bottom of the insulated shelter with a generous amount of clean, dry straw. Straw is superior because it repels moisture and allows cats to burrow into it, creating warm air pockets.
- Avoid Absorbent Materials: Do not use blankets, towels, hay, or other fabric materials, as these absorb moisture, can freeze, and do not provide effective insulation in cold, damp weather.
5. Secure the Lid and Weatherproof
Ensure the shelter remains dry and protected from the elements.
- Secure Lid: Place the insulated lid firmly onto the storage bin. For added security, especially in windy areas, use heavy-duty tape or bungee cords to keep the lid in place.
- Optional Outer Layer: For superior insulation and weather protection, you can place the completed shelter inside a second, larger plastic bin, creating an air gap between the two. Alternatively, cover the entire shelter with a heavy-duty tarp, securing it tightly.
6. Optimal Placement
Strategic placement maximizes the shelter's effectiveness and the cats' safety.
- Location: Position the shelter in a quiet, secluded spot that offers natural protection from wind and direct precipitation, such as under a porch, in a shed, or tucked closely against a building.
- Elevation: Elevate the shelter off the ground using bricks, wooden pallets, or waterproof cinder blocks. This prevents moisture from seeping in from the ground and adds an extra layer of insulation against cold surfaces.
- Entrance Direction: Face the entrance away from prevailing winds to minimize cold drafts and keep the interior as warm as possible.

Tips for Success and Maintenance
- Multiple Shelters: If you are caring for several cats, consider building multiple shelters to prevent overcrowding and reduce potential conflicts.
- Food and Water: Place food and water bowls a short distance from the shelter to keep the interior clean and dry. In winter, use heated bowls to prevent water from freezing.
- Regular Checks: Periodically inspect the shelter for cleanliness, damage, and to refresh the straw bedding as needed, especially after heavy rain or snow.
- Concealment: Camouflage the shelter with natural materials like branches or leaves to help it blend into its surroundings and provide a greater sense of security for the cats.
