Several voles, a few small birds, and, once, a live adder(!) We didn't actually realise that it was still alive, it was very limp and still, but we put it in a glass jar and left it alone for a little while, and eventually it started to stir. It was a small adder, but if it had bitten the cat it would still have been quite dangerous, I think... Silly, silly kitten. (This is the same cat who made friends with the neighbours' bunny - it broke out of its hutch and went hopping slowly around on our driveway, and the cat walked along next to it, looking for all the world as if they were involved in amiable conversation...)

They have also brought home a plethora of pine cones and leafs.
