So I've had 1 ball python, as a pet, living in a sterilite tub. I bought a 3 tiered rack to fit 2 more BPs in sterilite tubs. Is it necessary to "quarantine" the new ball pythons coming in, if I am stacking tubs on top of each other on my shelving unit? They are only pets, and all come from reputable breeders. If yes, how do I "quarantine"?
