Anytime unwanted dog/cat food (Keynsham and Bristol Areas)

Hi I have a very hungry Fox who visits my garden every night so if anyone has any out of date Sell by date food that they dont know what to do with i have 1 very needy Fox that would love it. I am a struggling oap and hate to see him so hungry and I have now used all my neighbours dog food that she didn't like plus some I bought cheaply but it's getting colder and he looks skinny and I am trying to fatten him up before it gets really. I leave my garden swing awning open at night for him to shelter in but he only looks in and then runs off but with encouragement he may stay to keep warm. So any treats would be great thanks.Roz.
