Double rex x double rex should produce all double rexs right..
Someday I'll keep accurate records, lol, I've done that breeding more than once.
If I recall correctly that pairing should produce 75% double rex's and the rest will be either standard coats or loose rex's
She's not a Siamese. Double Rexes lose their hair in odd places and keep them in others (usually face and rear keep some hair). She's black eyed which means she's not a Siamese. There are Black Eyed Siamese, but she's not one. They are still pretty uncommon.
Her skin was just like the black eye siamese. And over the night her skin is now a grey/blue. The nose still has dark color as so does her tail base. Im sure if i breed her back to her father a double rex siamese should come out eventually.
Shes shown no signs of growing her hair back just yet. Hope she dont and stays more hairless/thin fuz than her father.
