Dr. Work at Greenfield Vet Clinic does not know anything about tortoises! I took Gretta in for her re-check to make sure she is healthy after her case of hook worms, I normally work with Dr. Taylor but they put me with Dr. Work and after talking to him, I questioned him on his input aboiut substrate, just to see what he says and he told me toeither use PINE bedding or a carpet with Gretta!!! I couldnt believe what i was hearing!! I use coconut coir and sphagnum moss for her and she seems to be doing well with it and he said Im using an incorrect substrate for her. After he said that, I knew I was never going to let him see Gretta. He also told me she should be getting more protein than leafy greens. I know she needs protein, but shes a tortoise, she needs more leafy green than protein. He even gave me a box turtle care guide to follow when feeding, instead of at tortoise one.
