You may have to try a few times to get her to eat anything, and don't be too upset if she won't try anything. Poptart will only eat kibble, mealworms and watermelon. Everything else she considers to not be edible.
Some of Roses favorites: watermelon, sweet peas, sweet potato, green beans, carrots, apple, banana, pear, cantelope, etc. Vegetables are cooked and all are cut up in small bite size pieces or mashed.
