Here's why:
* Painful: Gerbils have delicate tails that are very sensitive. Holding them by the tail can cause them significant pain.
* Risk of Injury: A gerbil's tail is easily injured, and pulling on it can lead to broken bones, skin tears, or even loss of the tail.
* Stress and Fear: Holding a gerbil by the tail will cause it extreme stress and fear, potentially leading to biting or other defensive behaviors.
Instead of holding a gerbil by the tail, try these methods:
* Scooping: Use your cupped hands to gently scoop up the gerbil, supporting its body.
* Using a container: A small container like a plastic tub can be used to safely transfer the gerbil.
* Using a towel: A towel can be used to gently guide the gerbil into your hand.
Always handle gerbils with care and respect. Remember, they are delicate creatures that need to be treated gently.
