How to heat a cat house without electricity? Today we will answer this question.

Why do We Need to Heat an Outdoor Cat House?

To begin with, let’s figure out why you need to heat an outdoor cat house or cat shelter. You might think that if a cat has fur, it should be able to handle the cold.

Of course, the fur protects the animal from the cold and helps maintain body temperature. But in severe frosts, fur will not be enough. Cats, like people, can get frostbite or hypothermia. The chill is especially dangerous for kittens, senior ones, for pets with poor health. And our task is to take care of our furry friends.

If you want to take care of homeless stray furries, you can arrange not only cat shelters for them but also feeding stations. When it’s cold outside, good food and warm water help keep our friends warm and prevent colds.

How Cold is Too Cold for Cats?

It is impossible to accurately determine the minimum safe temperature for a cat. This is very individual and depends on many factors, such as age, body weight, health status, fur density, and habitual habitat (this can be a house or street). But there are approximate values ​​that will help you understand if the cat needs your help.

What temperatures can cats still survive outside?

For an indoor cat, the minimum temperature allowed is 45°F or 8°C.
For an outdoor cat, the minimum temperature can drop to 0°C or 32°F.
Small kitties or older cats should not be outside in temperatures below 45°F.

It is important to take into account not only the temperature but also the weather conditions. Fog, blizzards, and downpours create additional danger for our friends.

How can I keep my cat warm without electricity?

Street cats in the cold season definitely need a cat house. If it is not equipped with heating, you can use the following options:

  • Install heaters or heating pads
  • Use a sunroof to trap heat
  • Optimize air circulation
  • Keep it small
  • Use hay
  • Provide weather protection

How to Heat a Cat House Without Electricity? – 6 Tips

Now let’s take a closer look at the various ways to heat a cat’s house without electricity. For the best effect, some of these methods can be combined.

1. Set Up Heaters or Warming Pads

Cat warmers or cat heating pads are like little cat warm blankets or cat beds. They retain heat for a very long time and can provide a cat with several hours of warmth and comfort in his house.

They are of different types. Some require electricity. Such a pad can be heated at home, and then taken outside and put a warm pillow in the cat’s house. So you will provide the cat with a few hours of warmth and comfort.

If you are using electric heating pads, be sure to check them. The blanket should not be too hot.

There are also self-heating mats. They do not require electricity and they are safer. Animals themselves warm these pads with their own body heat. It is these rugs that are ideal for an outdoor cat house.

2. Use a Sunroof to Capture Heat

Even in autumn and winter, there are sunny days. Of course, this largely depends on the area where you live. But the sun can also help us keep the house warm.

Another way is to make a Plexiglas hatch on the roof of the house. This material is very durable and reliable. This design will be safe for the cat and provide him with warm sunlight during the daytime.

Of course, this option is only for those who love DIY.

3. Optimize Air Circulation

It is also worth paying attention to the air circulation in the house. If fresh air is not supplied to the house at all, the level of moisture will increase there, which will lead to the fact that it can be colder in the house than outside.

It is important that the floor has bedding that allows air to pass through and does not lead to moisture stagnation. The cat bedding should never be wet for long hours.

It is also better not to put the house directly on the ground. Under it, you can put boards or strong branches. You can also use a strong cardboard box. So dampness will not accumulate under the floor of the house. Some models of houses have special legs that provide the necessary air circulation.

4. Keep it Small

Pay attention also to the size of the cat house. Our fluffy friends don’t need a huge apartment! The size of the house should correspond to the number of your little friends.

Of course, a house for three or four cats should be spacious enough. But if you know that one or two pets will sleep in the house, don’t make it too big! In a small house, they will heat the air with their bodies, and the warmth will last longer.

5. Just Add Hay

Another way to keep them warm is using hay or straw. Hay is an excellent material for keeping warming and insulating. Spread hay on the floor of the kitty house and it will immediately become much warmer. In addition, hay is natural and absolutely safe. Most importantly, do not forget to change it periodically.

Of course, it will be unpleasant for cats to lie on hay, so you should definitely put a soft blanket made of pleasant fabric on top. The cat bed should be comfortable and not scratchy.

6. Weatherproofing

Weather protection and insulation are very important points for keeping warm in a cat house. This means that rain, snow, and moisture will not get inside through the roof and walls of the house. With good insulation from water and moisture, the cat mattress on the floor should not get wet.

Of course, this parameter should be paid attention to when buying a cat house. But even if you notice that the house is leaking, it doesn’t matter, it can be fixed.

If there are gaps or gaps between the boards in the house, they can be covered with special means, such as putty or sealant. You can find the necessary funds in any hardware store.
