The Polar Bears Aren't Happy

I just got an email of complaint from my polar bear sisters, although what they expect me to do about this, I have no idea. It was really warm on Friday when they left the house, so they consented to leave their blankets and quilts behind to leave more paw space for the others. Anyway, as it turns out, we've had a sudden cold snap. The human did get one blanket for them when they went by the house, but they emailed me to say it isn't enough, and they're going to freeze their fur off. Any suggestions as to what I should tell them? I so hope there weren't any quilts or quilting supplies left over at the hotel from that quilt show! I hope they hid the matches for the fire in the fireplace well too.
