How to properly pick up a cat by the scruff?

To properly pick up a cat by the scruff, gently grasp the loose skin on the back of its neck with one hand while supporting its hindquarters with the other hand. Lift the cat carefully and make sure to support its weight to avoid causing any discomfort or injury. It is important to only lift a cat by the scruff when necessary, such as when handling kittens or during medical procedures, as adult cats may find it uncomfortable.
