Some turtles like cheese.
Dairy products are not a natural food for turtles, and not very good for them. Turtles do not have the intestinal flora to properly digest dairy; and the cheese is too fatty for them. In addition, cheese is actually a poor source of calcium, because it also has a large amount of phosphorus, which inhibits calcium absorption (yep, that is true for people, too, but the Dairy Counsel won't tell you that :-).
Don't feed milk either.
