I have read Toms thread a thousand times. Yet, if I have the TRex food and the ZooMed dry grassland tortoise, are they not eating anything but the spring mix lettuce because those foods taste bad or what? I know I need to get the Mazuri brand. For the time being, I would like to use this food up if it is good for these torts. I just see them scarf down lettuce and nothing. I did spray the vitamin spray on the lettuce and they are still eating. They are also slowly chomping on the turtle bone. Thanks for your replys in advance.
