What should I use for now until I have the finances to afford a PVC enclosure? Some people say a 20L glass enclosure will be okay until she grows out of it. Any advice? Also I'm wondering if I need day and night light cycle. So I can see her in the cage at night without using a heat lamp unless I have too. Would something like this work?
