You guys might not believe this, because who will, but I trained my cat to play fetch. It took me months, almost a year. I was working really hard at it because I read that my cat's breed (Savannah Cat) could play fetch if they were trained well enough. Today, I was playing with my cat. I was tossing his little green mouse around, and then the craziest thing happened. Instead of waiting for me to come get the mouse, my cat picked it up in his mouth and carried it to me. After a couple other tries, it was obvious to me that my cat knows how to play fetch. You don't have to believe me if you don't want to.
