Mylar blankets are a cheap way to provide insulation for your outdoor cat shelter. These inexpensive safety blankets are reflective and direct the heat towards the inside of the shelter and will also insulate your pets from harsh winds and snow. Mylar blankets are thin enough to be mounted using a staple gun -- this allows you to remove the insulation when the warmer months arrive.

  1. 1

    Measure the dimensions of your cat shelter. This will give you an idea of how many blankets you will need to purchase to fully cover the exterior of the shelter.

  2. 2

    Unwrap the first blanket and align the top corner of the mylar blanket with the top corner of the first wall, from the outside.

  3. 3

    Staple the blanket in place with a staple gun. Staple the blanket every few inches to keep wind from going underneath the edges. Most cat enclosures are made of a wood frame which provides a good surface to staple the sheets to. If there is no wood frame to staple of the blankets to, place the blankets on the shelter and wrap several bungee cords or rope around the blankets to secure them.

  4. 4

    Staple the remaining sheets in the same way. Overlap the mylar blankets to prevent air and snow from seeping through the cracks. Continue the process until all four walls and the roof are properly covered.

Tips and warnings

  • Make sure you install the sheets of mylar from the outside because cats like to climb and claw things and can tear the mylar from the walls more easily if it is placed on the inside of the shelter.
  • Only keep pets outside when temperatures are above freezing (00 degrees Celsius) and limit their time outside when temperatures are closer to 00 degrees Celsius. Always monitor cats kept outside in enclosures. Kittens and old or sick cats should never be kept outside.
  • Always exercise precaution when using a staple gun. Wear protective gloves if you have never used a staple gun before.
