Hi..my tortoise stopped eating for 1 month,then i put few drops of multivitamin in her water and started giving her canned tortoise food not lettuce as usual, let her in the sun for ten min. almost everyday and placed a rock heater in her cage but she still doesnt eat...now it's more than40days since her appetite has changed ...dont know what to do. I noticed now that her limbs are spread out and head hidden, carried her and put her back but she's not moving!! Is she dying?
