I read somewhere that cats bring us "presents" to try and teach us how to hunt. They're very disappointed in us of course. The last cat that used to live with us did very little hunting. I think he was too lazy. Frogs from the next door neighbours pond used to appear now and again though. Cats also spray to mark their territory. What a stink! The male cat has a spiky penis, so that probably accounts for the noises when mating.
