Check your water pipes...let any faucets next to outside walls drip if necessary to keep water moving or at least open cabinet doors to the under sink water pipes to let in heat.
Give the animals some extra bedding. Block off wind.
I was always amazed at how animals can take the cold. Dogs' feet, cows' udders, sows' ears would all feel warm even on nasty cold days. Keep them fed, bedded, and out of the wind.
