Can you just put the cage on top of the rack? Unless you want to move some of the snakes, then there is nothing wrong with that in the least. Or get a shorter rack?

Not knowing all the specifics makes it hard...

I adore rats, and cannot imagine that I will ever not have any around, they really are the best pets.

Completely understand why you would want to have some back, and keep what animals will give you joy, you know that out there is someone who will give your snakes a great home if you choose to go that route.

Sorry you are making such a tough decision, but it is yours to make, no one is going to judge you (at least I cannot imagine that would happen).
