It's about time for me to upgrade my iguana's enclosure, and I'm thinking about converting a large wardrobe into a terrarium. This wouldn't be permanent, just something to last for the next two years or so, until I can build a full-sized habitat. I was wondering if anyone had any tips on the conversion. Also, most wardrobes I've seen that fit my size criteria say they must be permanently mounted to the wall. How necessary would that be for a terrarium? Is there something I can do to make it stable without wall-mounting?
