Sweet jesus, Kit the hare has learnt to rise to his back legs on signal. 
I am shocked and amazed. It was very easy in the end. He already knew it from years ago, I just put it on signal. I don't think he will ever be the kind of animal that comes out and performs tricks for you whenever you want, but having him respond to a hand signal is something I never thought we would achieve. I am going to try to film it today so I can provide proof for this outrageous claim, but as always, it depends on whether he feels like cooperating. 
For the record, I ended up dumping the clicker and luring without it. He had decided he didn't care about the clicker and would just get his strawberries his way. It was much easier and quicker to suggest ways he could achieve this with my body than with a sound, which I think is mostly because he spent so long learning my body language in minute detail anyway. It made more sense to him than sounds. It makes me think of that duck on Barking Mad they marker trained using a white card rather than a sound. Some animals apparently don't pay a huge amount of attention to sounds.
I would never make a good animal trainer. I'm so hungry for some level of communication that as soon as I realise the animal is asking for something I just give it. I'd be much more effective if I held off and expected something beyond just understanding one another.
