DIY: Warm Winter Cat Houses

Pet cats living outside and stray & feral cats have a really hard time in winter—those low temperatures can be deadly.  If your neighborhood has cats living outside and if your living situation allows, here are some inexpensive, DIY shelters you can make to give them a warm, dry place to sleep.

Obviously, don’t place the house where a dog can get to it, or where your indoor cats can see it, if your cats are threatened by strange cats in their territory.  Seeing a strange cat outside can disturb indoor cats and trigger redirected aggression where they attack other cats in your house.  If there are predators like raccoons, coyotes, bobcats, etc. in the area, cut a hole in the front and the back of the shelter so cats have a way to escape.

(Find instructions & materials needed here.)  The shelter intentionally tilted so that in case any water gets inside, the high end stays dry for the cat.

2tubshelterThe Ian Somerhalder Foundation (yes, that Ian Somerhalder) has a design for an insulated 2 bin house.  This is another easy one that doesn’t take much work or require many tools.  They also suggest lining the inner compartment with a mylar blanket to reflect the cat’s body heat.  These blankets are found in the sporting or camping section of discount stores.

  1. This is a fantastic idea! I have 2 wonderful kitty girls who HATE each other with a vicious HATRED!! One of them must live indoors; the other does very well outdoors. I will make one of these great shelters for that one! All winter long I stress about her getting too cold. Once she gets a house like this, I’ll be able to relax. Thanks!
