II really don't care what she is. She's friendly and beautiful and that's good enough for me
Unless you were interested in breeding her, in the future, that is all that should matter ... that you are happy with the purty little gal.
And if it is a creamsicle, I doubt this is a first generation of crossing, and as such the rat blood probably thinned down quite a bit.
If it will produce babies that look like him... I don't see the logic in calling it a creamsicle.
I also don't think creamsicles are that common, at least nowdays, corn snakes are very common and easy to breed- don't see a reason for people to unknowingly or knowingly produce hybrids and sell them as corns.
Creamsicles are not overly uncommon.
Perhaps much more uncommon, than Amel Cornsnakes, but they are not extremely uncommon.
I am sure there are quite a few cornsnakes, with questionable backgrounds, but ... I would find it very inappropriate to ~knowingly~ breed an intergrade/hybrid (or a labeled intergrade/hybrid), with a Corn, and sell the resulting offspring, as "pure" cornsnakes, without disclosing their intergrade/hybrid heritage ... &/or their suspected, or possible, intergrade/hybrid heritage.
BTW Although it may not make much sense, to do so, (considering your stated reason)... I feel fairly confident in saying that some folks do, knowingly (or with some suspicion of heritage), sell intergrades (50% corn, 75% corn, etc., etc.) as "pure" cornsnakes (That is, some do ~or~ have done so).
I am sure that some folks have unknowingly done so as well (cannot, of course, fault these unknowing folks, for what they believed to be true, if there were no contradicting evidence).
