I bought a Russian Tortoise yesterday and am not sure what food to feed it, as I have read that leafy greens have too much oxalates, so you should only give it to them once in a while, fruits and vegetables are only good once in a while, iceberg lettuce is devois od nutritional value, and the pellets that they sell at the pet store are not good to feed them as turtles do not like the taste and they are too high in protein. Even if there were leafy greens, I would not know where to buy them. Since the tortoises will get sick of a certain leaf, that means I am only to buy a few leaves of each vegetable at the grocery store? Or I guess I would need to buy a bunch of flower pots and grow them? Thanks.
