This right here is the reason I use a mass-produced machine-washable comforter instead of my beautiful antique bedspreads or my ancestors' handmade quilts. Look at all that cat hair! Because of the weird history of my house, the bedroom and my adjacent office stay plenty warm even when I set the thermostat at 60 degrees. Marshmallow will only get in the bed when there are no other cats there, but she loves the window table right over the heat vent. The view from there is nice, too. Apollo and Tommy stay in my bed most of the winter. Gatita will even come aboard occasionally.
