I like to check the pedigree on cats/boxes before I purchase, and not go by various claims of this and that trait hidden. However I see many cats on sale, showing no pedigree, this has been hidden from view, seller has not checked Enable In World Pedigree Link or not provided a pedigree.
No pedigree - is a no buy for me
What is the seller hiding
If you are no sure of hidden traits, you can always im or leave a notecard for the seller asking for more information or proof, as well as following Tad's advice and check The Dominance Charts
Watch out for Impossible claims about what is hidden
