Help the wildlife.
I was walking in Felden Tuesday lunchtime and I saw a huge fox pitifully searching for food in broad day light. After the walk, I rushed back, got a bag of dog food and went back to where I had seen him and sprinkled it in the undergrowth for him.
If your dog doesn't finish his/her food (or if you have some spare), take it on your walk with you and sprinkle it under bushes or in the undergrowth. If you have a cat that hasn't finished his/her food, you can put any tinned food on the bird table for the blackbirds, thrushes, carrion, sparrows, etc or under bushes for hedgehogs. (Avoid giving hedgehogs fish flavours).
If you are putting bread out for birds, soak it in some water first as water is in short supply for birds during frosty weather.
We built our houses on their habitat, so the least we can do is help our wildlife in this weather.
