Mousers is a term used to describe CATS that hunt and catch mice. It is derived from the verb 'to mouser, ' which means to hunt and catch mice. CATS have been used for centuries to control rodent populations in homes, farms, and other areas. They are also known for their agility and speed, making them excellent hunters. Mousers are often praised for their ability to keep rodent populations under control without the use of poisons or traps.
