BP New Home ? (Size vs Cage Size) 4 ft & 3 ft

[AKA Dave]

2 things to consider really IMO. I have several 4 footers and several 3 footers. I keep my males in the 3 foot units. They're just smaller snakes in general. The big girls get the larger spaces and the 4 footers are nice for breeding in if you do that down the road. If you plan on stacking them, get two of the same size. The sides take the weight and the tops won't sag over time. Just my two cents.
