Are they expensive to keep? I really want one but would need to learn more about them. Also, my school doesn't really allow mammals but they don't care really. It's my parents I worry about more. We have a cat, so I think they won't like the idea.

Where do you even get them anyways? I found an ad on CL selling one for $150, is that worth it?

Another thing. Do you keep the cages in the same room as your snake(s)? Would it put them in feeding mode all the time?
