Farm cats and barn cats have a great life. They are gainfully employed by the people who keep them. The employer supplies room and board and the employee, in this case, the cat, is asked for one thing in return:
If you see a mouse, catch it!
Here we have Socks, another of Suckee's orphans and the only male of the group. He went off to work as usual, and this day was a total success. He didn't catch a measly little mouse. He caught a big fat pocket gopher and played with it all afternoon.
