What do you think wild rabbits like Esther here have in common with badgers, weasels, rats and water voles?
All of them live in holes - but who lives in a hole like this?
It's actually the entrance to a fox den - home to Midnight...
...and her baby!
Foxes live all over the country, even in towns and cities.

But if you find a hole near to you, how do you know who lives in it?
Well, click here to get our Whose Hole? factsheet.

This will help you to identify a rabbit's warren, a fox's den and a badger's set.
Foxes live all over Europe, and not just in the countryside.

So if you find a hole - maybe under a garden shed, or in a park - print off the factsheet and see if you can identify who the hole belongs to.
The first thing to do is look how large the hole is.

A fox's hole will be between 20-30cm, a rabbit's hole will be smaller and a badger's will be a bit larger.
Also check out the heap of earth outside the hole.

A fox will leave a fan-shaped heap like this one.
But there's one tell-tale clue that will tell you whose hole you're looking at. And that's poo!
Many Brilliant Creatures use poo to mark their territory, and foxes are no different.
Fox's poo comes in different colours!

Foxes that live in towns and cities eat human leftovers, so their poo is a similar colour to ours - brown.
But foxes that live in the countryside eat mice and rabbits, and the bones that they eat as a result change the colour of the resulting poo - to white!
Here's some other types of poo to look out for.

This is rabbit poo...
...and this is badger poo.
If you think you've found a badger's set, whatever you do, don't disturb it!

It's actually illegal to do so, but it's fine to keep an eye on it, to see what goes in and out.
If you find a hole, drop us a line by e-mail to tell us what you've discovered.

We'd love to hear from you!
