I predicted this 3 years ago when I first say this species in petstores. Our local herp adoption has seen an influx on sulcatta's needing homes because of a)large size b)lifespan c)daily maintenence.

As most in this forum know, these animals need much more room than a herp society can provide, and with 10 months of the year being too cold for them outside the problem is just dynamite!
Here's a pic of a much more hospitable pet
