Why Outdoor Cat Shelters Matter
Outdoor cats, whether they are truly feral or simply outdoor-access pets, face many challenges. Harsh weather conditions are a significant threat. Extreme heat can lead to dehydration and heatstroke, while cold snaps and prolonged freezing temperatures can be life-threatening, especially for kittens or older cats. Rain and snow can soak their fur, leading to hypothermia. Beyond the elements, outdoor cats are also vulnerable to predators, parasites, diseases, and traffic accidents. A well-built shelter provides essential protection from these dangers. It offers a sense of security, a place to escape stress, and a warm, dry resting spot, significantly improving their chances of survival and well-being. Knowing you’ve provided such a vital resource is incredibly rewarding.
Choosing the Right Location for Your Cat Shelter
Selecting the perfect spot for your outdoor cat shelter is crucial for its effectiveness and the comfort of its occupants. Think like a cat! They prefer locations that offer both safety and convenience. Here’s what to consider:
- Protection from Wind and Elements: Position the shelter so its entrance faces away from prevailing winds, typically north or east in many regions. This minimizes drafts and keeps rain and snow out. A natural windbreak like a dense shrub, a large rock, or the side of a building is ideal.
- Elevated Placement: To prevent flooding during heavy rain or snowmelt, and to offer better insulation from the cold ground, place the shelter on a stable, slightly elevated surface. Even a few inches can make a difference. Consider a pallet, sturdy bricks, or a raised platform made from scrap wood.
- Accessibility for Cats: Ensure the cats can easily reach the shelter. Avoid areas that are difficult to navigate, blocked by dense undergrowth, or too far from their usual territories. They need to feel safe entering and exiting.
- Away from High Traffic: Keep the shelter away from busy roads or areas with a lot of human or animal activity. While some cats might be used to people, a quiet, secluded spot offers them peace of mind and reduces their stress levels.
- Sunlight Exposure (Seasonal): In colder climates, a spot that gets morning sun can help warm the shelter naturally. In very hot regions, provide shade for the shelter and surrounding area, perhaps under a tree or bush, to prevent it from becoming an oven.
- Water Source Proximity: While not essential, placing it reasonably close to a food and water station (kept separate from the shelter itself) can encourage use by stray cats.
Essential Materials and Tools
Building a basic outdoor cat shelter is surprisingly simple and doesn’t require a trip to a specialized lumber yard. You can often use reclaimed or leftover materials, making it an eco-friendly and budget-conscious project. Here’s what you’ll generally need:
Materials:
- Container: A sturdy plastic storage bin (at least 18-20 gallons is a good size for 1-2 cats), a wooden crate, or even an old cooler. Ensure it’s watertight.
- Insulation: Styrofoam sheets, rigid foam insulation boards (like Polystyrene or Polyisocyanurate), or thick cardboard can be used to line the inside walls and roof.
- Bedding: Straw is the best option for insulating bedding because it repels moisture and stays dry. Avoid hay, as it can mold. Old blankets or towels can be used for inside, but they need to be removed and cleaned regularly during wet weather.
- Connectors/Fasteners: For wooden shelters, you’ll need screws or nails. For linking multiple bins or securing insulation, heavy-duty waterproof tape or silicone sealant can be useful.
- Optional: A reflective, insulating blanket (like Mylar space blankets) can be an extra layer. PVC pipe or scrap wood can be used to create a hinged lid for easy access.
Tools:
- Measuring Tape: For accurate measurements of materials.
- Cutting Tool: A utility knife or box cutter for cutting insulation and cardboard. A hand saw or power saw if working with wood.
- Drill: For creating an entrance hole and ventilation holes.
- Marker: To mark cutting lines.
- Sandpaper: To smooth any rough edges, especially around the entrance.
- Safety Gear: Gloves and eye protection, especially when cutting or drilling.
Step-by-Step Guide: Building a Simple Bin Shelter
This method uses a common plastic storage bin, which is waterproof, durable, and easy to work with for beginners. It’s a fantastic way to provide immediate shelter.
Step 1: Prepare the Bin
Choose a good-sized, sturdy plastic storage bin with a secure lid. Aim for a dark color, as it absorbs less heat in the summer. Clean the bin thoroughly if it’s used. Measure the dimensions to decide where to place your materials and cut your openings.
Step 2: Create the Entrance
Decide on the size of your entrance. For a typical adult cat, an opening of about 6 inches by 6 inches is ideal. This is large enough for them to enter comfortably but small enough to keep out larger predators and the elements. Using a drill with a hole saw attachment or carefully cutting with a utility knife, create the entrance on one of the longer sides of the bin, about 4-6 inches up from the bottom. Smooth the edges with sandpaper. If possible, position the entrance slightly off-center. This allows the cat to hide from view once inside.
Step 3: Add Ventilation
Proper ventilation is vital to prevent moisture buildup and maintain air quality, especially in summer. Drill a few small holes (about ¼ to ½ inch diameter) near the top of the bin, on the opposite side from the entrance, and maybe under the eaves of the lid. This allows stale, moist air to escape and fresh air to enter without creating a draft on the sleeping area.
Step 4: Insulate the Shelter
This is a key step for warmth. Cut pieces of rigid foam insulation board or thick cardboard to fit the inside walls, floor, and lid of your bin. You want to create a snug fit. You can use silicone sealant or strong, waterproof double-sided tape to secure the insulation panels. Ensure there are no large gaps where cold air can seep in. An extra layer of insulation can be added to the floor for better ground temperature regulation.
Step 5: Elevate the Shelter
To keep the floor dry and insulated from the cold ground, elevate the bin. Use sturdy, weather-resistant materials like concrete pavers, bricks, or pressure-treated wood scraps. Place them under the corners of the bin to create a stable base. Ensure the bin is level. This elevation also prevents rain and snow from accumulating around the base and potentially seeping in.
Step 6: Add Bedding**
Line the floor of the insulated bin with a generous amount of straw. As mentioned, straw is ideal because it traps air and repels moisture, staying dry and providing insulation. Avoid hay, as it can become damp and moldy, which is unhealthy for cats. A thick layer, at least 4-6 inches deep, will make a cozy bed. If you choose to add a blanket, make sure it’s easily removable for cleaning and drying, as it can absorb moisture and become a health hazard.
Step 7: Secure the Lid
Ensure the lid is securely fastened. If your bin lid is loose, weigh it down with rocks or use bungee cords to secure it to the bin itself. If the bin has a hinged lid, consider adding a latch or even using duct tape to seal it shut for winter, ensuring it’s still accessible enough for cleaning or checking on the cats.
Advanced Options and Variations
Once you’ve mastered the basic bin shelter, you might want to explore other options. These can offer more durability, space, or aesthetic appeal.
Wooden Shelters
Wooden shelters can be built using plywood, lumber scraps, or even an old wooden crate or pallet. The basic principles of insulation, ventilation, and elevation still apply. You’ll need to cut pieces for the base, walls, and roof, then assemble them with screws or nails. Ensure all wood is treated or painted with a non-toxic, waterproof sealant to protect it from the elements. A sloped roof is ideal for directing water runoff away from the entrance. You can find excellent plans and considerations on resources like Alley Cat Allies’ Building a Cat Shelter guide.
Multi-Cat Shelters
If you notice multiple cats using your shelter, you might consider building a larger one or linking multiple bins. For larger structures, consider multiple entrances and exits to prevent cornering and promote safe passage. Two openings on opposite sides can be very beneficial. Insulating and elevating remain paramount.
Hinged Lids for Easy Access
For easier cleaning and maintenance, especially with wooden shelters, consider building a hinged lid. You can attach the lid to the back of the shelter using sturdy outdoor hinges. This allows you to lift the lid for inspections and relining with straw without having to dismantle a section of the shelter.
Internal Dividers
For very cold climates, an internal “halo” or divider can be added just inside the entrance. This is essentially a small wall that creates an offset entrance, providing an extra barrier against wind and cold air entering the main living space of the shelter. It’s like a little mudroom for the cats!
Maintaining Your Outdoor Cat Shelter
A shelter isn’t a one-time build; it requires some ongoing care to remain effective and safe for the cats. Regular maintenance ensures it continues to provide a healthy environment.
Regular Inspections
Periodically check the shelter for damage. Look for cracks, loose parts, or signs of wear and tear from weather or animals. Ensure the lid is still secure and the insulation hasn’t shifted or degraded.
Keep it Clean and Dry
The most critical maintenance is keeping the bedding dry. Straw is excellent as it naturally repels moisture, but if it becomes damp, it needs to be replaced. Remove and discard wet or soiled straw promptly. This is crucial for preventing mold and maintaining a healthy environment. In very wet conditions, you might need to check and replace bedding more frequently. Consider placing a piece of plastic sheeting under the straw that extends up the sides a few inches, creating a waterproof basin.
Pest Control
Over time, shelters can attract insects or rodents. If you notice any pest issues, address them immediately. Avoid using chemical pest control methods near or inside the shelter, as these can be harmful to cats. Instead, focus on keeping the shelter clean and well-maintained, which naturally discourages pests.
Seasonal Adjustments
For summer use, ensure adequate ventilation. If it gets extremely hot, some cats might avoid the shelter. You can add extra shade to the area around the shelter. For winter, double-check insulation and ensure bedding is dry and plentiful. You might consider adding an extra thermal layer to the lid.
FAQ: Your Questions Answered
Here are some common questions people have when thinking about building outdoor shelters for cats.
Q1: How big should an outdoor cat shelter be?
A1: For one or two cats, a shelter around 18-24 inches long, 12-18 inches wide, and 12-15 inches high is usually sufficient. A larger space can be harder for cats to warm up with their body heat. A common size for a bin shelter is a 20-gallon storage bin.
Q2: What is the best material to use for insulating a cat shelter?
A2: Rigid foam insulation boards (like Styrofoam or Polystyrene) are excellent because they are waterproof and provide great thermal resistance. Thick cardboard can also be used as a temporary or additional layer.
Q3: Should I put a door on the cat shelter?
A3: A simple entrance hole is generally best. Most DIY shelters don’t have traditional swinging doors, as these can let in drafts and make it difficult for cats to enter quickly. A slightly offset entrance can provide a windbreak.
Q4: What is the best bedding material for outdoor cat shelters, and why?
A4: Straw is the best choice. It’s a fantastic insulator, repels moisture effectively, and stays dry. Hay should be avoided as it holds moisture, can become moldy, and is less insulating when wet. Avoid cloth bedding like blankets and towels as they absorb moisture and can lead to chilling.
Q5: How do I keep the shelter from getting too hot in the summer?
A5: Ensure there is adequate ventilation with holes near the top. You can also position the shelter in a shaded area or add a shade cover over it. Avoid dark-colored bins if heat is a major concern; lighter colors reflect more sun.
Q6: How do I discourage pests from living in the shelter?
A6: Regular cleaning and replacing bedding is key. Ensure the shelter is elevated off the ground. Avoid leaving food scraps near the shelter. If pests become a significant issue, consider a more robust construction that is harder for them to penetrate, or consult local animal welfare organizations for advice on humane pest deterrence in animal shelters.
Q7: Do I need to worry about predators getting into the shelter?
A7: A properly sized entrance hole (around 6×6 inches) will deter larger predators like coyotes. Elevating the shelter can also make it harder for some ground-dwelling predators to access. For added security, consider a shelter with two entrances/exits, allowing cats an escape route if they feel threatened.
