There are three types of waste products that a Ball Python produces.
1) Urine. It is wet and it really stinks. If you are using aspen, sometimes it will sink to the bottom of the enclosure and the top layer of aspen will dry off and you may not realize that you have a "puddle".
2) Urates. It is soft (initially) and white. It can dry into a hard lump, but you will usually not smell it.
3) Feces. It is soft or hard and brown/black. It stinks like poop. Sometimes (especially if you have aspen) a snake will hide its poop. Many like to poop in their hides. If your snake's poop does not look "normal" then you may have a problem that needs a VET to look at.

They go when they feel the need to go. Could be once a week, or he.she could hold on a couple of weeks. Has the snake eaten while in your care?
