Sammy, what pretty coloring you have, and we can see why you mom fell in love with you at first sight! It is good she got you and Sunny at the same time, as we ow rats are social animals! It is fun you have such a strong personality, and are the outgoing one, and I bet you have a grand time meeting new people, and charming them so Sunny can stay in the background, as she is not as brave as you! It is cute you like having your tummy "attacked" - and we know forms scientific studies that rats actually not only like being tickled, but giggle - just at a pitch we humans cannot hear! Congratulations again, pretty Sammy!
