I have two sphynx cats and in the past have had to put heating pads under their sleeping quarters. This bed is perfect, is quality made, keeps them toasty warm and washes beautifully. I'm glad to see that it is advertized, here, closer to it's actual length of 18 inches, as elsewhere it's advertized as 22 inches in length, which is false. None the less; whether it's 18 or 22 inches, it's perfect.
