Before getting a leopard gecko, it’s important to assess whether or not they are a good fit for your home, and a common concern is “do leopard geckos smell?”
Leopard geckos themselves do not smell, and I consider them to be a very clean pet. They will usually poop in the same area of their enclosure, and then they avoid this area (so they are not trampling in their excrement and getting germs on themselves).
However, their poop can start to take on a bit of a smell if it has been left for a few days, so it’s important to clean their tank/ vivarium regularly. For me, I can only smell it when I open the vivarium door, so even if it does start to have a little bit of an odour, it does not make the entire room smell.
As long as you are prepared to clean them out frequently, this will not be a problem, and I wrote a post explaining The lazy way to spot-clean your leopard gecko’s vivarium so you can quickly and easily clean out the poop in around 1 minute.
