This is terrible, I like badgers and I don't want to join the CA...

I wonder if this would work

According to a bloke I spoke to a few months ago, the badgers who are currently digging out one of the North East's few remaining barrows do so in order to remove soiled bedding.
"They're very clean animals" quoth he, "They clean out their beds every day"
If this is why badgers keep digging, despite having large enough setts, perhaps all those who say they're going to end up out of work if hunting with dogs is banned could be employed to replace the bedding in badger sets. The badgers wouldn't need to keep digging, the CA is slightly happier and the heritage is not going to get as wrecked.
The obvious problems such as: "how do you change badger bedding without disturbing the sleeping badger?" and "How do you get in there in the first place?" could be solved by spurious genetic modification of hunt attendants to make them very small, with extra enzymes coded in to make them smell like badger chambermaids.

If I was a badger, I'd be happier digging in a nice newly created pile of earth specially prepared a good distance away from the nasty old piles of earth which would get all spooky due to Nigel's mole scarers.

Each badger costs 3000 pounds apiece to relocate! Bless their furry socks, I love them!
