sandy, foxes cache food so it will take the fat blocks and bury them if it is full of dog food.
I've had foxes in my garden for nearly 30 years without a problem. Bird food is put out of reach of them, no killed cats in the area but I have watched them catch rats and mice. Before we had wheelie bins we had to put black bin bags out for the dustmen and it was the magpies and seagulls that attacked them, not the foxes. Now we have wheelie bins there is no problems like that.
We still have plenty of frogs and newts in the garden at certain times of year but sadly no hedgehogs. That is due to the badgers who love to eat them.
My friend has a huge family of foxes living in her huge garden and has wildlife photographers come to take advantage. One of my favourite photos of hers shows a fox sitting in the middle of the lawn watching a photographer erect a hide. She does feed the foxes but always keeps her distance.
She feeds them tinned dog food and dog sausages which she hides around the garden. She also has an online diary which is enjoyed by thousands of people around the world which documents the daily lives of the photos, with photos. So far none of her neighbours have complained and some come to watch the cubs. I have a photo showing 13 foxes sunbathing in her garden.
Foxes do make spine chilling noises at certain times of the year, it is true.
