Can a Robo get a 1/2" diameter ball into its food pouch?

My Robo, Dusty, was playing in his playpen today and he was trying to chew a wooden ball that came off a hamster toy. I measured it and it is 1/2" in diameter. Is this a choking hazard for him?

It's possible he could pouch it. I would just not use it and remove it to be on the safe side.
