It's good to see that all the breeders of hybrids and locality mixes are keeping such good records and not misrepresenting non pure animals.
What if you see he parents and they look like they are both probably jungles? Would that be enough for you to say that this animal is a pure jungle? You can't tell what this is with certanty, so what makes the parents identifiable with 100% certanty?
Threads like this should pretty much negate any opinion that hybrids are fine as long as the breeders and every owner represents the animals knowingly and honestly. It never happens.
