Heated beds are safe for cats just like electric blankets are safe for humans. However, it is important to ensure your adhering to the manuals instructions on the do’s and don’ts. For example, some heated bed manuals strictly prohibit the use of additional extension cords. This is because the available extension cord may not support the level of electricity the heated bed needs to operate. This could eventually lead to the cords burning out or even worse, spark up a fire. So the electric bed itself is safe, but you need to thoroughly read the manual and comply with the safety regulations.\r
