I have my baby panther in a 2x2x4 cage, no dividers, no risers, no modifications, BUT it is heavily planted and "twigged" along with larger sturdier branches. The twigs allow him to move about in his cage as he pleases, the 3 pothos give him plenty of shade and more climbing and hiding and drinking opportunities, I do have a feeder cup in the cage to allow him to eat as many crickets in the same area as he pleases. The whole 2-3 cage thing is a little bit extreme in my opinion. Provide food, water, space with adequate climbing opportunities and watch him grow! Mine has been in his big cage since I got him in December and is doing great. I plan on adding another cage to his cage when he's one to maximize his space
