I currently have a Vivarium for my Hermanns tortoises and I am aware that these are deemed to be unsuitable for them. I am a student and do not have a lot of money to spare but thinking for using a indoor rabbit cage for them. I have seen other people use them and they have been perfectly fine, my only concern is as to how I would fix my lighting in. I already have UVB strips and a basking bulb with a reflector. Photo below shows setup I want to buy.
