If your turtle is reluctant to eat, try soaking or misting before feeding. Make sure the turtle is warm enough. Reluctant feeders can often be enticed with live food such as an earthworm or slugs, or colorful foods such as strawberries or cantaloupe. Sick turtles will usually not eat well, so if the turtle refuses to eat for more than two weeks, seek veterinary care. This should convince your turtle that you are a good provider.
Good lighting is important physiologically and psychologically.
An additional incandescent bulb will be appreciated for its warmth and light. Set the incandescent bulb so that it warms one area of the terrarium to about 85F. Turtles that do not see light for at least 12 hours a day can stop eating and become inactive. Box turtles do well at a wide range of temperatures. Twice daily sprinkling may be required in hot, arid regions.
