If you really want the ball as badly as you say you do, stop bringing it back to the Human who tosses it across the backyard, away from you, again and again and again.
When you find yourselves outnumbered by the Meowies, stand very, very still, save for the wagging of one of your tails, which they may or may not interpret as a white flag depending on their knowledge of canine signals, the strategic importance of your physical location, and their mood.
Uh-oh, we seem to be blocking access to the Meowies’ kibble.
