    Feed your turtle a balanced diet.Your turtle should eat a balanced diet comprised of fruits, vegetables, and meat. If your turtle is aquatic, its diet should be 65% to 90% meat (e.g. earthworms, snails, mollusks, frozen pinkie mice, dried turtle food/pellets) and 10% to 35% vegetable based (e.g. mustard or collard greens, grated carrots, grapes, mango, cantaloupe). If you have a box turtle, its diet should be 50% meat (crickets, mottled mealworms, slugs, snails) and 50% vegetable based (e.g. berries, green beans, winter squash, flower heads).
    • Young turtles need more meat than more mature turtles.
    • These are general rules for turtles, but the diet will vary depending upon the species of your turtle.
    • Always feed your turtle fresh foods.

You can supplement calcium by giving your turtle calcium blocks, cuttle fish bone, or powder. Give your turtle supplements once a week.
    • Place the calcium blocks or cuttle fish bone in your turtle's habitat for you turtles to gnaw on them.
    • You can also coat your turtle's food with calcium powder before you give it to them.
    • You can also give your turtle a reptile or turtle multivitamin twice a week.
