No Constraints Carpet
Pink Tentacle has a blurb about Panasonics hot pet carpet friends, this sounds like a job for a crafty arudino maker –

At the Tokyo Fiber exhibition in Omotesando last weekend, Panasonic unveiled the “No-Constraints Carpet” (tentative product name?), an innovative hot carpet with the warm, fuzzy appeal of a beloved pet. The carpet’s luxurious coat of faux fur (available in white, brown, or skunk-like black and white) houses a set of smart heating elements that deliver warmth only to the areas you touch when you cuddle it.
