Instead of leaving the base with the cold glass, it is better to place a substrate or floor that is suitable for the type of pet you have. This allows the animal to dig and tunnel as it would do in its natural environment. Another advantage of a substrate is that it provides a more natural environment, keeping your pet calmer and helping them feel at home.
Below we can classify the most common ground materials into three types:
Calcium sand: for more desert animals, which require minimal humidity.
Coconut fibre or pine bark: for tropical pets.
Mosses or leaves: ideal for terrariums with warm climates.
