Urban foxes are sourcing more than a third of their diet from humans – raising concerns they could face health risks from processed foods.

Scientists at Nottingham Trent University analysed the whiskers of nearly 100 foxes to reveal that food sourced directly or indirectly from people made up 35% of city fox diets, compared with only 6% for their country cousins.

Foxes are omnivores that eat a range of foods from small mammals, birds, beetles, grubs and worms to fruit and carrion.

The study used chemical analysis of the whiskers of 93 dead foxes across Britain to reveal what they had been eating over a period of weeks to months as the hairs grew, rather than a snapshot of dietary information gained from looking at stomach contents or faeces.

We live in the future.
