Don't use Eco Earth Loose coconut fiber substrate.

[PitOnTheProwl]

For those who own a ball python like me: Many of the impaction problems can be avoided or even preventive by following one clear rule: Don't Feed your snake in it's enclosure!! When you feed your snake you should feed it in a separate feeding container such as a box or Plastic tub and for Christ's sake use tongs. Why are you feeding your snake in the enclosure in the first place? For one by doing this every time you open the cage your BP is going thinks it's feeding time and become CAGE AGGRESSIVE.

Please enlighten me on either of these WRONG thoughts?
There is plenty of dirt, leaves and other items in nature that they swallow in the wild.
Aggression on feeding in their enclosure, I have not had any problems.
