Radiated tortoises that sit inactive and inappetent in a corner for a longer period of time show unmistakably that they are in a suboptimal housing situation and/or do not feel well. Check honestly and self-critically the offered housing conditions. Also read and study the recommendations for keeping the animals described on this website (especially regarding light, temperature, humidity, hygiene and food). If there is no improvement after the elimination of possible deficiencies or husbandry errors, it must be assumed that the animals are already seriously ill. In this case, consult a specialized veterinarian within a reasonable period of time. With early detection and prompt treatment, the chances of recovery are better.
