Paula's right - ancestral genes will often appear in so called "domestic moggies"
Cats in one litter can also have different fathers because of a process called superfecundation. It's a fascinating subject.
Moray has Lynx-like ears too, and a huge fluffy tail. He is the spitting image of a pedigree Norwegian Forest Cat, but he's not. Makes no odds to me. I love him to bits, and Frieda and Ralph can be Royalty if they want to be.
Lynx ears are usually found in longhaired breeds like Maine Coons, Norwegian Forest Cats etc. so maybe some of that in his ancestors, my Barney was a moggy but everyone said he looked as if he had a oriental head. With mixed breeds and genetics it's impossible to tell. The main thing is that they are dearly beloved and in a good home now.
