Whenever a Dog or Cat enters the battlefield under your control, create a colorless Treat artifact token with "{t}. Sacrifice this artifact: Target Dog or Cat gets +1/+1 until end of turn. You gain life equal to that creature's toughness."
{t}: Create a 1/1 white Dog creature token or a 1/1 black Cat creature token.
