Essential Tips for Building a Weatherproof Cat Shelter
No matter which design you choose, keeping your shelter weatherproof is key. Here are some important tips:
Use Proper Insulation
Straw is one of the best materials because it repels moisture and retains heat. Foam boards are also effective.
Keep the Entrance Small
A smaller opening prevents cold air from entering while keeping warmth inside.
Elevate the Structure
Always raise the shelter off the ground to avoid water damage and cold surfaces.
Add Waterproof Layers
Use plastic sheets, sealants, or roofing materials to protect against rain.
Choose the Right Location
Place the shelter in a quiet, wind-protected area such as near walls, fences, or covered patios.
