With all the heating pads that are being sold on the market, you might think it’s not a problem for a cat to use one, but you have to pay attention when you allow your cat to enjoy that warm embrace a pad gives it. Heating pads are safe for cats as long as they are specially made for cats.
The difference between cats and humans is that they like to play with wires and sometimes chew on them. The pads commercialized for cats have safety features that the other ones don’t, like cords resistant to chewing. You can also regulate their temperature and it is not a problem if they get wet, because they are water-resistant.
You can also buy the non-electrical version, which you can heat inside the microwave. They can keep your cat warm for at least 12 hours during the night inside, but outside they will cool faster.
