• Defined as the areas of air exchange between the air inside the leopard gecko's enclosure and the air outside of the gecko's enclosure.
  
  
• Ventilation is a key principle when setting up your gecko's enclosure.

How do you provide the necessary ventilation?

• The most common way of providing the necessary ventilation with a glass aquarium is the use of screen tops/lids.
  
  
• In custom wood enclosures, you may need to make your own vents using screening, pegboard, plastic vents, household vents...etc.

Why is ventilation important?

• Poor ventilation can make your gecko's habitat unhealthy and can lead to a variety of health problems including:
  
  - respiratory problems
  - bacterial infections
  - fungal infections
  - skin problems
  
  
• Improper ventilation becomes an even more critical health problem when combined with improper temperatures and poor cleaning/disinfection techniques.
  
  
• Ventilation will directly affect your environmental temperatures and humidity levels in your gecko's enclosure.
