He could be a she. It doesn't matter to me really what sex he/she is. Its just strange because he/she did stop growing for a while at 3.5 inches and has not made any call sounds but when we brought him/her home he/sh made a cheeping sound an diid growl at me once when I tried to get dirt away form his/her eye. From what I understood females make no sounds at all. Except like grunting sound which I have never heard.
