Two blankets minimum, and I have to be at least 2 feet above ground at all times. I have agreed not to sleep in the bed with you two maniacs anymore because you're always kicking me in the gut or head or smushing my paws under your fat thighs. But I refuse to be on the ground like a peasant dog. This wool lined safety seat that allows me to hover above Tofu in her igloo bed provides the appropriate elevation. Best of all, I can continue looking down disapprovingly at her because she is a second class citizen. I am glad you finally made me a personal sleeping area that meets my standards. Now if you don't mind, I have 3 hours of napping to do before you make me a snack.
