Normals can have green/silver eyes too. Petsmart and petco all sell captive hatched animals. Meaning, they catch wild gravid females, hatch them at the farms in africa or here in the states, and sell the offspring.
They go through many MANY hands, and both the people in Africa and here in the US know a special animal when they see it. If it was a high gold animal, it is not a pastel.
Also, how did the BREEDER tell her it was a morph if she bought it from Petsmart? That's very contradicting. Private breeders do not sell to petsmart.
I think without a pic, it's impossible to say what it is. My guess it's a normal.
