My tortoise haven't eat anything for one and half week and he is always hiding but not sleeping.
Terry Allan Hall said:Offer him a piece of red food...bell pepper, red lettuce, shredded carrot, whatever you can find. The color red seems to mean "food" to most tortoises. If you have access to Mazuri Tortoise chow, soak some in water that has been tinted a strong red w/ food coloring.
Once you find something that get's your tortoise interested, mix it in with his/her regular food.
