I need help (well the tortoises do) I was feeding Mazuri maybe once a week (wish I never even did that) and now they just want Mazuri. My one redfoot refused to eat anything else for weeks but Mazuri and maybe a few bites of the regular spring mixes, fruit, mushrooms, squash..now my other 2 just want Mazuri as well...I had to separate the one that would not eat so I could watch her to make sure she eats and when I offer her Mazuri the other to walk away from their regular food and try to climb over the divider to the other tortoises food to the point they are flipping over and going insane...how do I stop feeding this stuff, my one tortoise won't eat anything else now and now they all just want Mazuri...I don't want them to get sick, or starve to death
