I've had my sub-adult RF for about a month now, he will rarely eat any greens, and won't touch the few squashes I've tried. He will eat watermelon, cantaloupe, cherry tomatoes, strawberries sometime, cherries, and he loves meat, lean roast and albacore. Should I only offer him greens hoping he will eventually get hungry and eat them. I feel bad doing that but he's acting like a spoiled kid. I've tried different kind of greens, escarole, radicchio, zucchini, yellow squash, cilantro, beet greens, dandelion leaves, collard greens, spring mix... He'll look at the greens all day but eat albacore right out of my hands like he's starving. I know he's supposed to eat 70% greens. Any suggestions on something he won't turn down?
