Neither. He's a non-pedigree.
I wish that people would stop making the assumption that a blue cat equals a pedigree breed. Yes, Russians are blue (but also come in black and white), BSH come in blue (but also just about every other cat colour under the sun) and non-pedigrees also come in blue. That's because the two recessive genes that produces blue cat (non-agouti and dilute) that turn a "bog standard" tabby cat into a solid blue are endemic in the general non-pedigree population, not just in pedigree breeds.
A blue cat has two copies of the recessive a (non-agouti) gene that turns tabby into black, and two copies of the d (dilute) gene, which then turns black into blue. The latter is the same gene that turns ginger into cream and chocolate into lilac. Both parents must carry the gene and pass it onto their offspring.
Both of my past and current blue cats are non-pedigree.
Thanks. I have had several BSH down the years but don't confess to being an expert on pedigrees at all. I just love cats 🐱
