I have a WC California kingsnake that I have had since I was 5 years old, so he was collected in 1992. I was too young to remember if he grew at all after being caught or if he was an adult, but I think he may have grown a tiny bit before leveling out, so he was probably born in '89 or '90. He is a little guy, weighing in at 220g and being just right about 3 ft long. He is happy, healthy, has never bitten me in 18 years, and still has it in him to fertilize eggs (although the one good looking egg out of the clutch unfortunately went bad). I'm now getting into snake breeding mostly for the sake of continuing his legacy with another generation before he dies, as I too am wondering how much longer he has. The good news is that I now have 4 breeding-size females, so he will be getting busy a lot in the spring if he lasts, which I think he will.
