So we have a pea lover.....well at least that is green. So here we go. Try offerring only peas....with the pod. Also, all of the greens mentioned above.....have a strong taste.
Ideas, Rainbow Collard Greens....try giving him the veins (sneek in a few green parts in too

Also, I know this might sound stupid...but balling up the greens into something that resembles the shape of a "pea" might just work.
My girl loves a Romaine mix, collard greens, BLUE BERRIES (she loves them), crickettes worms, peas, corn and seeds......I avoid too many insects or highly water saturated foods like the peas, corn and blueberries too much.
A Uro. is so easy to spoil, they need to think its the 2 year of the drought of the century... befor they will eat what you put in front of them!
P.s. = My Uro. Sweetie looks at me like I just pulled her tail first out of her log.......if I even think of giving her iceburg lettuce. go figure....
