When is a Beaver not a Beaver?

[DozyDonut]

Ok, bit random, but we are just watching the one show and it's about Beavers, cute little things with big teeth and build wicked dams,
DH wants to know why a ladies foo is called a Beaver
He says they have no similarities atall which I guess is correct. I said I had no idea so he told me to 'ask my mumsnet people, someone will know!'

So dear ladies (& men) what is the answer?

Perhaps some women have teeth in the wrong place

Isn't it about fur - beaver fur was an expensive item used in coats etc, so a similar derivation to 'muff' (though muff is a bit more visually obvious as well).

Vagina dentata

Some of these explanations are entertaining:

American thing, small furry animal. Beaver, pussy.....

Because they sleep all day? And cause mass destruction to wood?

Because they chew on wood, surely?

Loving the answer 'they eat wood' on the link above!

Because they are furry and hard working.
