Dominant to Foxie - Blondie.
This one is tricky because it takes a few pedigrees to show the Blondie has to be pure.
First up heres the baby
Next is Salems pedigree
His parents are full siblings so only posting one of them here because they key cat is Salems Grandad.
So Bronas parents are Blondie & Shaun. Shaun is the one here to show that Salem has to be pure because Blondie is also his mother
Ok so Shaun has his Dads Shown fur which means he hides either Blondies Shown Platinum or her unknown hidden.
Since Salem parents are both Platinums that had to come from either Blondie or Shaun if he hid her Shown fur, when Salems parents passed their hidden furs it had to be the same fur because Shaun hides either Blondies shown or hid so if he passed Burmese Platinum the Foxie Blondie was Blondies hidden fur and she passed it, however if his hidden was Foxie - Blondie it had to be Blondies hidden fur. Therefore since the only available furs from Shaun and Blondie have to be His Burmese - Sable (lost in Salems parents) Her Burmese - Platinum or her Hidden we can conclude that Blondie Hides Foxie - Blondie and its the most recessive fur either cat can pass therefore Salem is a pure cat as both his parents had to hide it from one of theirs.
Sorry for such a long convoluted explaination if anyone disagrees please yell out
