so my leos cage has a bad smell that will not go away matter how much i clean out the nasty and clean the area that she goes in it still seems to hold this odd bad smell i have taken everything out and cleaned it well and after a day or two it still smells the same, i have slate tiles with a little sand around the edges where there where spaces in the slate, i can tell its much more smelly when she has done her deed but after i clean it up the smell is just lingering, "she" is still prety young, could it be that she might be a he and is marking his things? thanks for any help
