I'm with rufretic on this one; it's literally baffling to see some of these figures and even more baffling to see that the majority of people spend $150+ per animal on just housing.
I mean, to each their own as far as what you're willing to spend on housing and it definitely depends on how you want to display your animals (tubs and racks vs. terrariums, etc.) but wowsers.
It seems obvious to me at least that the majority of people that keep more reptiles generally start needing to spend less on husbandry items - it's sort of like buying in bulk at Costco to illustrate my point a bit more.
