What should you grasp to effectively remove a mouse from its cage?

Grasping the base of a mouse's tail is the correct approach for safely removing it from its cage. The reason for this technique is that the tail is specifically designed to handle weight and support the mouse's body without causing stress to its spine. When you hold the base of the tail, you are able to safely lift the mouse without causing harm or panic.

In addition to safety, this method allows for a more controlled interaction, which is especially important in preventing accidental bites or escapes. The mouse can feel secure when held in this manner, as it is less likely to thrash around, which can occur if it feels insecure or frightened.

Other methods, such as grasping the middle of the body, the tips of the ears, or the back legs, could predispose the mouse to injury or distress. Holding the middle of its body might involve pressure on the abdomen, which can be uncomfortable. Grabbing the ears is not advisable, as they are sensitive structures, and this method can lead to pain or injury. Similarly, holding the back legs can be ineffective and stressful for the mouse, making it harder to manage safely.

Thus, holding the base of the tail is the most appropriate and safest method for handling a mouse during such interactions
