I guess I should have mentioned...
...that my cats can't get to my snakes because my snakes are all in rubbermaid enclosures. I used to have my snakes in aquariums, but several factors caused me to change to a rack system. One of those factors being that one of my cats liked to get on top of the screen. I was always afraid she would fall through. Other reasons include...easier sheds and the rack takes up less room! Anyway, I think that if you keep a close eye on <b>ALL</b> of your animals, then you should be fine. If any of them seem to be stressed by the other animals, then simply try to keep them apart.
