OMG! You are JUST identical to my Calvin and Hobbes. I adoped them in 1997 and they looked exactly like you two! Of course the were both brothers but Hobbsie grew up to be a 20lber and Calvin 10lbs! I eventually got to recognize them by Calvin's sleek fur and big white inside huge ears and Hobbes had rougher fur and all black even in ears.
Concatulaions Max and Ruby on your COTD! Keep your family and especially your own personal dawg under your knowing paws! Yay!!!
