Gecko Poop – What’s Normal And What’s Not?

Most geckos have small, damp, cylindrical poop that is approximately ¼ inch long, accompanied by a smaller quantity of solid white urate. Any changes in the color or texture of the poop can be a sign of an underlying health issue or an aspect of the gecko’s care that needs to be tended to. Many geckos usually leave their poop in a trail down the glass surfaces. If you have a bioactive enclosure, the brown and white poop and urates can be cleared up by isopods and springtails, but you will still need to use reptile-safe spray to wipe the glass.
