The Goof Gene
As if there was not a strong enough familial resemblance between Cat and the boys.
Those of you who have been with us since the very beginning will recognize the first and last pictures here as they were pulled from Dax's journal (September 27th, 2005 to be exact). And, yep, that's Devin in the middle making the same face his brother made when he was about the same age.
I really think it has to be genetic.
