Here's what I did with over the 200 Calabars that I had:

1. Always used Panacur and Flagyl first
2. Cypress mulch 9 inches deep in a 40 gal. cage. They like the weight of the substrate on top of them
3. 250w red heat lamp on top. Thermoregulate by depth
4. Filled a large crock with 20 mouse fuzzies. Most gone when left overnight. Stay away from adult mice or rat pups
5. Kept 2.6 per 40 gal.
6. Leave them alone. No handling
7. You're not going to believe the size of the eggs

Good luck,

Mitch
