I didn't feed any formula yesterday and today when I was fixing their salad I alway lay 2 or 3 larger pieces of collard greens/romaine in the bottom of the dish with a little hanging over the edge and then top it with very small chopped greens and the soaked pellets. I hadn't even finished getting everything in the dish when 2 little guys ran up and started nibbling on the greens that were hanging over the sides of the dish!!! They are so cute!
