I was gone for 2 wks and came home to a different Opo. Opo gained over 300 grams and almost a inch in length. Opo's head is much bigger and legs. I gasped when I picked Opo up. I used to pick Opo up with 1 hand and my fingertips would reach around the shell. Now my fingertips can't get underneath. I would like to say Opo missed me but Opo just cares if I keep the food coming.
