Lizards grow throughout their lives. Their
tough outer skin doesn’t grow to accommodate them
so they shed to expose new (and looser) skin.
How often your gecko sheds is related to how fast
she is growing. She’ll shed less often as she gets
older. If you are interested, you can chart how
often your gecko sheds and how fast she grows.
Ideally, you’d want to know the surface area of
her skin but that’s hard to guess – you could
measure her length or her weight instead.
You are also growing and shedding your outer
skin, but in much smaller patches that are hard to
see. Dead skin cells are actually a significant
component of dust around your house. You can (and
hopefully do) help this shedding process when you
shower or bathe. Similarly, if your gecko is
having trouble shedding, you can help by providing
a humid hiding hole or a bowl of water. When in
doubt, consult a veterinarian. For more

Geckos and other lizards often eat their shed skin
– it’s actually a sign that your gecko is healthy.
They do this for a few reasons: 1. Growing that
skin was a lot of hard work and there are lots of
minerals stored there. By eating the skin, they
can use the nutrients to grow new skin. 2.
They eat the shed to hide from predators. In the
wild, shed skin would alert other animals that a
lizard lives in the area. 3. Even lizards like to
keep their territory clean. They don’t like living
a dirty enclosure any more than you like living in
a dusty room.
