Sulcata enclosure I made, looking for advice/suggestions/criticism!
I made this box for our two female sulcatas. They’re a little under a year old, maybe 9-10 months.
The box is 2x4, with about a 1x2 section covered with a heat lamp in the lid, then roughly 2x3 open air section covered with wire mesh to keep predators out. Base is a mix of coco coir and reptisoil, with a couple hides. How much longer do you all think they can stay in this size enclosure? They will eventually have a larger area of the yard fenced off for them but will this be good until they’re 2 years or so? Wanted to wait until this coming winter to renovate the yard. Thoughts or suggestions?
