They have theirs in too small cages as wellThey will also be selling them. If you look half the time they will be missing toes or tips of their tails because of cage mates, and when they get older male and male will fight, male and female, male WILL breed female to DEATH, and female and female might work, but there are still dominance issues and it rarely works out. Two beardies need a 6x4x2 cage, and if you cannot provide it, then stick with one beardie. Just like humans they love space that they might not even use, if you were sharing a a bed room with lets say your wife, and you just got a new house, would you pick the smallest kid bedrooms or one of the bigger ones?
