I'll let the video speak for itself.
I've now had girls Sissy and Pia 3 years which I adopted from Metro Ferals and the boys Zorro and Stanley 2 years. As you may remember the boys were born across the street around June 2006 and trapped by Alley Cat Allies around November 2006, their first winter of '06 the stayed on my patio and I provided cover. Zorro was easy to get to know and then pick up, I would feed them outside and the girls, who never go out, inside. Now everyone eats inside. The boys still go out for awhile but have found out that being inside is a better life.
