A.J. (the one in red) picks out the ones she does not want and puts them by the bowl, then takes the one she does want and carries it over to the potty pad

and proceeds to eat it. Now Emma (the one in pink) likes the tiny ones that A.J. does not eat and picks them up off the floor and comes and sits by my feet wherever I am and eats it. Funniest thing them eating like that. Neither eats at the bowl.
My newest one, Karma, eats at the bowl and the other two look at her like she is the one that is nutty
