When you’re building your housing, you want to find an adequate substrate for the floor of the tank or the cage. The most common substrates are paper towels, newspaper and Reptile carpet. It is considered most prudent to avoid sand because of the risk of the gecko ingesting it.
Paper towels and newspapers may not look the best but they are safe and easy to replace. They also have the added benefit of making it very easy to see waste and know when you need to clean your gecko’s home.
Reptile carpets are also a nice soft surface that your gecko cannot accidentally eat. They are washable and environmentally friendly as well. It is often a good item to get two so that you can switch them out for easy cleaning.
One of the main things to avoid is any substrate that your gecko can eat or can get caught on. These can cause injury to your gecko and are best avoided.
