Nope, I don’t know. He was a stray cat until the shelter picked him up.
Paul is so handsome! I would describe him as a seal point and white domestic shorthair.
Purebred cats of other breeds do sometimes show up in shelters and rescues. However, as W Willowy mentioned, there are almost no Snowshoe breeders in the United States at this time... this breed has almost completely disappeared. So the likelihood that Paul would have Snowshoe breed ancestry is extremely small. It's most likely that he is simply a seal point and white domestic cat that resembles a Snowshoe. That doesn't make him any less special, however... he's still a gorgeous cat
