Thanks. That makes me feel better I was sure it must be right-I'm just paranoid and this is my first (as an adult) pedigree cat.
I had to phone the breeder to get some info that I forgot to ask last week and she was happy to tell me and had a chat about the kittens, she told me the pedigree prefix although I'm sure I misheard it lol.
I'm 100% confident now. And off to tidy the house some more and re string the cat tree and clear the tops of bookshelves.
It's all very exciting.
Thank you all for caring to respond.
