This is my sully tub as im still working on it but if anyone see something i can improve on please let me know as im still learning. It contains cypress mulch about 8 inches deep so they can dig and i can make them hills to walk on. its a 4 ft long tub purchased at Tractor Supply. it gets mist everyday and torts as well. I curently house 3 Sullies in this enclosure, they love it and have exercise room I also have a outdoor enclosure for them for spring and summer time.
