No - we don't put food out as that attracts rats. We live in the centre of town with a main road in front of the house and an industrial park behind us. Yet we still see urban foxes and have bats hawking over the garden on summer evenings. Plenty of birds and insects too. The way to get wildlife in your garden is to provide a totally chemical free environment with plenty of cover and native plants. A pond is essential too.
