>>19094230It is a genetic trait. Where their fur is different than other parta of their body that has totaly different genes
you can can take 2 dna samples, one from where the fur is grey and one from where they fur is orange and it would come back and the two samples would indicate that they are not from the same cat.
Same shit is valis for humans too. Thats why some dna maternity test can come back as the mother isnt the mother of her child genetically even tho she gave birth to her
