Most of my life has been spent in a rural setting or in neighborhoods with 3+ acre lots and with a cat and dog as pets (sometimes pigs and chickens as well). When Tim and I married, he too had a cat, so we elected to keep up that tradition with having "live mousers" in our home.
Currently, we have 4 barn cats. They stay outside most of the time, and come inside for safety during the night hours. They also keep us company and can be found nearby whenever we are outside playing or working.
