I do believe Tanner was getting into the tub and eating Ollie's food. Ollie has moved into a room of his own, with a baby gate blocking the door, so Tanner no longer has access to his food.
Tanner is playing with Ollie, but still enjoys his special morning playtime, while Ollie is in his room. Tanner loves to run through his tunnel and jump for a string! I think we'll see a loss this next week with his weight.
