Don t try to guess the temperature - you will either end up with a snake who will be too cold to eat and digest its food or one ill or dead from overheating. No special lighting is needed. Balls are nocturnal snakes, spending their days in the wild securely hidden away from possible predators. To make it easier to see your Ball during the day, you can use a full-spectrum light or low wattage incandescent bulb in the enclosure during the day. Make sure the snake cannot get into direct contact with the light bulbs.
Balls are very prone to getting seriously burned.
Feeding Allow your snake to acclimate to its new home for a couple of weeks. Older Balls may be fed larger pre-killed mice or pinkie rats. If you have not had any experience force feeding a snake, you may not want to try it yourself until you have seen someone do it. If your new Ball has gone several months without eating, and is beginning to noticeably lose weight, take it to a reptile vet or contact your local herpetology society and ask to speak to someone who is knowledgeable about Ball pythons and feeding problems. Check it daily and change when soiled.
