I know I said we weren't going to rename our female rabbits that turned out to be male, but we've since thought better of that casually arrived at decision. They are now known as Tolkien and Trigonometry. Ailz came up with Tolkien- something to do with hobbits and living in burrows- and I came up with Trigonometry because I thought it went superbly well with Tolkien. Also it was the first thing that came into my head- and sometimes the first thought is the best thought.
Tosh and Trigonometry have bonded- leaving Tolkien out in the cold- and subject to random violence. For a while we had him in a separate pen, but now we've gone the whole hog and moved him outdoors- where he has a shed as a burrow and the whole, well-walled yard to run about in. He seems to be happy. If this arrangement works out we may eventually get him a (properly certified) female companion.
Here Here he is, doing the rounds of his new domain.
