That's correct for a 4x2x1, I was figuring 4x2x2. I don't have an adult ball, so I wasn't sure about its requirements. Mine is still in a 15.
So just so I don't mix up further, I'm reading that you have an RTB in a 4x2x1 with climbing branches and a heat lamp?
My RTB doesn't use his hides very often, but will burrow and climb on his branches. He's the only one I have equipped with a heat lampI use 4x2x1 cagesRTB forums are a good resource for information. A lot of guys on there use cat litter pans for hides. I suggest the OP should check them out. They have many ideas for large hides, cage requirements and all that.When they are fully grown, hides become difficult to come by that will fit them
