My apartment gets really cold too. I ended up getting a Thermo Kitty pressure-activated warming pad to tuck under Smudge's blankie on the platform rocker, since he's so floofy that clothes would just squish his fur down and reduce its ability to keep him warm. He loves it! He's snoozing on it right now. Later he might relocated to the end of the bed, which abuts the wall of the boiler room, but his... I mean the living room chair with the warming pad is his favorite napping spot when it gets really chilly down here.

Love, Columbine
