Best way to keep crix

[ThEmAdHaTtEr]

Hey all. I have been buying 20 large crix every other day from petsmart for about a year now. I really dont wanna do it anymore. I've been thinking about buying them in bulk and breeding them in my garage but my parents won't let me (I'm 14). I asked if I could keep them outside the house and they said no because it attracts the spiders. Anyway, any suggestions as to what I might do? Thanks all.
