Dogs can stay comfortable as long as your home is at least 45 °F (7 °C). If the temperature really starts dropping, your pooch may start shivering or whining.

This DIY sweater works best for big dogs, but you can still make an easy no-sew sweater if you have a small dog. Just cut one of the sleeves off of an old sweater or hoodie and cut off the wrist-end so the sleeve is the same length as your dog. Then, cut out two half circles, one on each side of the sleeve, to make the holes for your dog’s front legs. Slide the sweater over your dog so their head goes through the narrow end and their front legs go through the small holes. [9] X Research source

Birds can survive in temperatures between 50 to 59 °F (10 to 15 °C), but they won’t do well below that. If your bird fluffs up its feathers and doesn’t eat, there’s a good chance that it’s cold. [12] X Research source Move your bird’s cage away from any windows in case any drafts blow in. [13] X Research source As an extra precaution, keep your bird cage away from candles, or fireplaces—these can give off smoke, fumes, and vapors that are unpleasant for your bird. When the power comes back on, keep your bird away from any space heaters, as these also create fumes.

You don’t want your pet to chew or eat the hot packs by mistake. Most reptiles need an environment that’s somewhere between 75 to 85 °F (24 to 29 °C). [15] X Research source

If the aquarium temperature sinks to around 55 °F (13 °C), pour warm, dechlorinated water into the fish tank. Only change the water temperature by around 10% every 1-2 hours, so you don’t disturb your fish.

You can buy propane heaters from home improvement or big-name retail stores. These heaters don’t need electricity to run, which makes them super useful during a power outage. Some ranchers feed their livestock more to help them stay warm. [18] X Research source
