This is so sad for you... it makes my blood boil that people are taken in by scammers like this. My kittens go at 13 weeks with the works. Unfortunately people go on sites like pets4homes and see the mast-head adverts, they then contact these people... I know that one of the catteries that advertises has been struck off from all the major registries!!! But does the general public know... cos not! If anyone wants a pedigree kitten they must go to the breed sociaty websites and look from there, it isn't 100% nothing is but scammers do get outed and will be expelled from them!
Unfortunately a four/five generation pedigree from an unregistered kitten is worthless; all the crooked breeder has to do is look online and take some names off other breeder's websites, as many put their cat's pedigrees on.
One of my buyers told me when she picked her kitten up that kitty was related to a cat she had brought last year, I was horrified to learn that her cat was the son of Charlie Boi... Chaz had never fathered the litter... he was/is a nueter!!! So her pedigree was a work of fiction... unbelievable!
I don't think you will ever get kitty registered, as the breeder doesn't register her cats, it will be impossible for the GCCF to validate the paperwork. Enjoy and love your kitten, have him neutered and if you want to, then show him in the pedigree pet section, I know loads of people who do this, you can go into the master cat classes.
