My little rat boys are four months old now and they are growing like weeds! Pnigel continues to be the smart, adventurous, friendly one, while Simon is more reserved, shy, and I hate to say it, but simple minded. I love him just the same, but he's not the sharpest little guy. Pnigel loves to have me pet him and will even leave one of his favorite special foods, spaghetti, to come and say "hi". Look at his sweet little face and the tomato sauce on his hands. Doesn't he look as if he's about to say something?
