Wait I thought it was Caesar that Doflamingo was trying to keep from falling in the wrong hands, not Vegapunk. Anyways, I think Kaido just likes Zoan DF users and has been recruiting only Zoan DF users in his crew. But now with these artificial DF's he can build his army quicker. Also about your theory about being able to command animals, it's possible that his DF allows him to speak to animals but not necessarily control them.
