Interesting, thank you those who have replied!

Thank you Raven01 for the suggestion I have found someone else already who I will be buying from in Ontario.

I'm wondering now if it would be best to buy the side-by-side enclosure rather than the stackable enclosure - to save money, as well as control the heat better (since I have two different species with different needs, stacking could be tricky). My worry is that the ball python will be too cold. Right now he's got a heat bulb on him... mind you, he's in a glass vive with a mesh lid so none of the heat stays in. If I were to get stacking vives, even though they save a lot of space, I don't know how I'd integrate another heat source for him. I don't think a second UTH would be sufficiant for his ambient air temp.

I have no other concerns with the corn snake, though

Any other advice would be appreciated!
