International Cat Care run some “negative genetic registers” and the GCCF run some “active registers”. For cats to be placed on these registers the sample (mouth swab or blood sample) MUST be taken by a vet who confirms the cat’s identity using its microchip number. The microchip number must be written on the submission form AND sample.
We have a dedicated submission form for this purpose, which both the owner and vet must complete. The certificate will state that the cat’s identity was confirmed by a vet and you can use this to register the cat with the ICC negative or GCCF active registers.
If a breeder DOES NOT want their cat to go on these registers then they can take a mouth swab and submit it directly to the lab.
