Local pet store has a black belly high white cal king - they keep upping the price every few months, they've had it since October and are asking way too much - and won't take any adults ever again. It's a beautiful snake, they just want too much for it - and it's not a baby, people want to buy babies.
I'm not blaming the pet stores for small corns, but either the big mass breeders are breeding them year round (very possible) or they find a way to keep them small (IE lack of feeding) as baby corns I've seen tend to grow like weeds - at least when fed.
What's also interesting, I never see normal corns in typical pet stores - not even Okeetee. Reptile specialty shops, sure, but never the small pet stores that happen to carry reptiles. Every corn is a morph. Every freakin' one.
Normal cal kings are rare too - only normals I've seen in my local pet store were some stripers (and they looked like desert stripe, so not sure if that is "normal" unless it is that rare scissor crossing locality) - and the one banded I sold them.
In fact, one employee noted she had never seen one with real nice bands like that and no striping - every "banded" they get shows some aberrancy. She thought I selectively bred it! I guess she doesn't look at the DORs that can be found from time to time on the major road right by the pet shop ... as their banding is just as "perfect"
