But our favorite: feline thermal units (or FTUs)! To you, they may look like ordinary house cats. But as warm blooded mammals, they give off a good bit of heat. While heat and air conditioning are often measured in BTUs (British thermal units), we’ve converted from BTUs to FTUs.
Our FTUs come with other nice features: soft fur, a pleasant meow, and deep purrs (they have a 4-stroke motor – after 4 strokes on the head or back, they start a gentle yet strong purr). They also come with 4-on-the-floor, pointed ears, and a sandpaper tongue – all standard equipment.
So, whether watching TV sitting on the couch or sleeping in bed, before we turn on the heat, we take advantage of our FTUs!
