Well actually it's "pi" not "pie." I noticed this the other day and pointed out his markings to Arvin who was delighted because he loves math and has even memorized pi to some huge number of digits. Duma seems oblivious to his amazing mathematical side. He continues to pursue his favorite things - eating, sleeping, and playing. As a result he has reached the amazing weight of 13.4 pounds at 11 months of age.
