Heated Donut Bed — USB, Constant Warmth

Winter means your cat takes your bed.

A cat looking for warmth finds the warmest thing in the flat, and from November that is you, under the duvet, at three in the morning. This is a deep plush donut bed with a low-wattage USB heating element inside it, so there is somewhere warmer than your side of the bed for her to go.

Warm without heating the room: A low-watt element warms the bed itself rather than the air, so she gets a warm spot without the radiator running all night.

Runs off any USB socket: Plugs into a phone charger, a plug adaptor or a laptop — no dedicated mains unit, no batteries to replace.

Raised rim to curl against: The bolstered edge gives her something to tuck her head and spine into, which is the shape cats sleep in when they're cold.

Deep plush pile: Long-pile fabric holds the warmth in against her instead of letting it escape through a thin base.

Somewhere better than your duvet: Give the warm spot a fixed address and the three-a.m. negotiation over your legs stops being a nightly event.
