My cat, Luke, loves to play fetch. When he wants to play he'll drop his mouse at my feet and meow at me. I throw his mouse and he brings it back. If he's in the mood, he'll will sometimes even want me to throw it in the air so he can jump and catch it midair. I don't know how he learned to play fetch cuz I didn't teach him. One day he just started doing it and has ever since then.
