What does the pig catcher primarily do?

The primary function of a pig catcher is to allow for safe capture and restraint of pigs. This tool is specifically designed to facilitate the handling of pigs during situations where they need to be managed for various purposes, such as veterinary checks, vaccination, or other health care procedures. Ensuring the safety of both the animal and the handler is crucial, particularly because pigs can be strong and unpredictable when frightened or stressed.

A well-designed pig catcher minimizes the risk of injury to both parties by providing a means to hold the animal securely without causing harm. This is essential in agricultural practices, as safe and humane handling is a key aspect of animal welfare. Tools or methods that do not focus on this aspect would not align with the primary use of a pig catcher, making it clear why the chosen answer reflects the most accurate function of this equipment.
