1. Insulation & Space:

   • Use straw only (do not use hay or other materials as it can get wet and freeze) for effective insulation, turning the shelter into a warm haven.

   • Keep the shelter compact for better warmth retention and always plan for more cats than you initially spot.

2. Safe & Stealthy Placement:

   • Position shelters in hidden spots, ideally behind barriers, and ensure entryways are obstructed to deter unwanted guests.

3. Shelter Design:

   • Elevate the base slightly to ward off cold and dampness.

   • Design a small entrance for warmth conservation, but large enough for accessibility. If adding a secondary exit, ensure non-opposing placement.

4. Protection & Dryness:

   • Add a plastic awning for extra insulation and safety.

   • Slightly slant the shelter to prevent water accumulation and maintain a dry interior.

5. Stability & Internal Care:

   • Secure lightweight shelters using flat rocks or weights.

   • Prioritize straw for internal insulation, avoiding moisture-retaining materials like blankets.

2. Line the bin with Styrofoam.

3. Place a snug-fitting smaller bin inside, carving matching doorways.

5. Add a Styrofoam roof and secure with the bin lid.

Remember, while this shelter is low maintenance, occasional checks for cleanliness are essential.

By following this guide, you can ensure outdoor cats have a warm and safe haven throughout the winter months.

BONUS STEP

If you want to make your shelter more inviting to the kitties, sprinkle a little catnip in and around it. If the kitties are going to deal with the cold, they might as well have a good time while they’re at it!
