I like the fact that they are basically a stackable aquarium, with the front opening for easier cleaning...I like the recessed top, and the different accessories you can use. My concern is heating, the only heating option seems to be a spotlight fixture, but I don't like bare hot bulbs in the cage, both for the animal's safety(I keep mainly snakes) and as a fire hazard in case you use newspaper or something flammable...is there any way to use belly heat in these without resorting to a hot rock...I guess you could put a dome light on top, but then you couldn't stack them...any ideas?
