So long as you are providing food for your snake it won't go crazy because it smells rabbit funk (it wouldn't go crazy anyway). It is the same thing how aquariums keep sharks in with other fish. Your snake isn't going to loose its mind because some rodent lives in the same room. Now if you have a full grown reticulated python that has not eaten in 6 months and you have rabbits loose in the same room it is loose in that would be another story.
In short don't put your snake in the rabbit cage and you should be just fine![]()
