A mouse!

Sometimes Woschech the cat brings mice at home. I'm not talking of the dead ones which lie sometimes as a gift for me on the threshold, I'm talking about living mice. Best toy cat ever, as they're still running. I always try to catch them and set them free and usually I get them.
Woschech is not very amused about it, of course. 
But I'm as good as him in catching mice.
