She's very pretty! A lot of people in Europe tend to confuse run-of-the-mill domestics (moggies) with the European Shorthair breed, which might be why somebody said your cat is a European long hair. Domestic medium or long hair would be the apt description.
Even our vets, who should know better, have our moggie listed as a European Shorthair, which he definitely isn't, since he has no papers.
Thanks guys. Id never heard of European long hair before it was said to me. Id always presumed she was just a domestic long hair. Thanks for clearing that up :-)
