They will do this almost every time they shed.
They eat their shed skin for a number of reasons. The main reason is that when geckos shed, they are losing lots of nutrients and minerals, through the lost skin and the fluid they had to produce to shed it. They eat the skin to gain some of these nutrients back. This will help them to generate a new, tough protective layer in the future.
Another reason is that eating their shed skin is actually a survival instinct in the wild. Leaving the shed skin may attract predators. Since it would usually be kept near the gecko’s den, it can lead the predators to the geckos themselves. Geckos eat their shed skin to avoid detection, even though they have no predators to worry about in your home.
Your gecko may also exhibit shedding problems if he becomes ill or stressed. Always be sure that your gecko has adequate hiding spaces and visual barriers to keep him feeling secure, and visit your veterinarian periodically to ensure he is in good health. External parasites – especially mites – can lead to poor sheds as well as other health problems, so monitor your pet for their presence.
