I have a neighbor who wants to rehome their 3lb male sulcata. I have three others of a smaller size that were rehomed to me. They of course are and would be separate until I can garuntee gender and size compatability. I have around 2,097 square feet for them. There are a lot of visual barriers. For the cold months, I would split the attic and basement between them. I plan on using pond liner and/or plywood to contain their subtrate...the attic has a shaggy purple carpet about 2in. The people who lived here before us were strange. Do you think the 2,097 square feet would be enough to house four sulcatas? They would be in a yard that size for 6yrs. give or take. That is until we move somewhere with more land. I cannot find anyone who wants a male sulcata in my area. I could take it, but I do not want to crowd them.
