We provide enclosures and husbandry that matches the snakes' natural environment as closely as possible. We want them to feel secure and be healthy. Naturally, these snakes do not cohab unless for breeding. They don't have dens, they don't hang out with each other, and that's the way they have been doing it for centuries. No need to try and change that now. It just adds stress and can lead to health problems for them, and monetary problems for you.
