See, I loved my balls in tanks...and I got a seemingly endless supply of them at little or no cost....but that was when my collection was a mere 5 snakes.......My collection has grown so large, this is the best,most timesaving,easy and most spacesaving way. Not to mention, my buddies at the pet store are always calling me with someone who wants to get rid of a snake-with a tank. I've adopted four ball pythons in the last year...
