Unless your breeding I don't see much of a point...funny thing I was talking to my partner about this yesterday about this..I just my first two and that's good enough..I give them there own time but also take them out each about 3 times a week and let them slither round my apt,under my supervision ofcourse and I keep them in tanks where they can hunt and explore,if they choose etc...not in these racks that are just cruel,IMO,you can't enjoy them as pets. They just sit there,get fed and that's that. Like I said if you breed and have racks I get it,if not I don't. My partner at work actually said unless breeding it's not fair keeping them in racks,alot of people feel this way,but most are scared to say anything.
I'm not trying to be rude, but I don't think i'd formulate such strong opinions with as little experience as you have.
You keep your snakes in fish tanks? Does this mean you'd keep fish in snake racks?
