My 4 years and 10 months old male ball python is currently 4 feet long or almost 4 feet long. Would he reach 5 feet in the future or he will continue to grow in girth only? I,m asking because i just built for him a new enclosure, size in feet: 2 long, 2,62 deep, 3,30 high. I am wondering if this enclosure size would be enough for him forever or i will have to upgrade in the future?
