We have a heated birdbath, but I didn't think to put my heated dog bowl out for the wildlife. The squirrels were trying to use the birdbath earlier, so I'll put the dog bowl out. In addition to our feeders, we usually put out corn for the critters. We support a feral cat and I managed to trap him to bring inside. Poor thing is cowering in his basement accommodations, but better safe inside than frozen. We are also running the faucet at a trickle overnight, and keeping the dishwasher door open. Not sure what else we can do inside. Our temps will be at zero tomorrow with wind chills 40+ below zero. Can't wait until the weekend when we're back in the 30's!
