How do I know if my gecko is cold?

You can tell if your gecko is cold by observing its behavior. If it is seeking out warm spots in its habitat, such as basking under a heat lamp or heat mat, it may be feeling cold. Additionally, if your gecko is sluggish or not moving much, it could be a sign that it is too cold. It's important to monitor the temperature in your gecko's habitat to ensure it is within the appropriate range for their species.
