Yes it can! For cats to be placed on the negative register with organisations such as ICC or GCCF 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. Our result certificate will state that the cat’s identity was confirmed by a vet and you can use this to register the cat on the ICC negative register.
If you DO NOT want your cat to go on these registers then you can take a mouth swab and submit it directly to the lab.
