Remember, when setting up outdoor winter cat shelters, it’s crucial to consider insulation, weatherproofing, and proper placement. Regular monitoring, adequate food, and fresh water are also essential for the well-being of outdoor cats during the winter season.
There are multiple resources online for building winter shelters. Here is one of our favorites from Alley Cat Allies.
Here are some general tips you can keep in mind:
- Insulation is key: Strong insulation is needed to trap body heat during the winter. Never use fabric as that will draw body heat away from cats. Use straw, never hay. Line your shelter with mylar. It's inexpensive and its reflective qualities will generate additional heat for the cats.
- Size and location are important: Try to be efficient with the size of the shelter. The smaller the shelter, the less open space there is to let cold air in. Make sure that your shelter is placed in a safe spot. It should be somewhat hidden. The entrance should face a wall whenever possible to keep the wind from blowing cold air in.
- Don't place the shelter directly on the cold ground: This isn't always feasible in colonies. For that reason, we usually insert a styrofoam cooler inside a plastic tote. That gives the shelter an extra layer of warmth. You can also use 2x4s, bricks, etc. to raise it off the ground.
- Make the door as small as possible: Cats only need an opening of five or six inches in diameter - roughly the width of their whiskers. A small hole will keep predators out and encourage cats to feel safe. Place your entrance off-center so that a cat can burrow over to the side and stay out of any draft.
- Create an overhang: You should create an overhang over the entrance of the shelter if it is directly exposed to the elements. This will keep snow from piling up in front of the entrance, making it too difficult for the cat to enter or exit.
- Make sure your shelter is weatherproof: Your shelter needs to be completely weatherproof to avoid moisture. You can wrap it with a plastic trash bag or heavy plastic sheeting to make sure it stays dry. This will also give you protection from the wind.
