In general, older models of electric heating pads are much less safe than are newer models and are more likely to result in a house fire. Older models may lack an automatic shutoff, allowing the pad to overheat and start a fire.

Overall, cat heating pads are relatively safe, so you won't have to worry about them causing damage to your cat or your home. In fact, most cats will think of it in the same way and find it comforting. They can also provide an easily accessible place for older cats who might get a little stiff during the colder months.

The heating pad should come with an automatic shutoff to protect your dog, but in the case of malfunction, you need to be there to protect your dog. Malfunctioning heating pads have been known to severely burn or even kill dogs. Don't let your dog lie directly on the heating pad. This can cause a mild to severe burn.
