Gina,
How old are they now. You should be able to tell by 6 weeks old. Have they been to a vet yet because they should be able to tell what sex they are. Plus they need to get started on the vaccination series. I breed Maine Coons and there are standards for each breed of cat, ie Scottish Folds Persians ect. I woul have to see head type body type ect to check to see what standard it meets or may be close to. But without registration papers they will be concidered a DSH or DLH. I would love to see pictures as they grow they have wonderful color and patterns to them. And if they are as nice as I think they are you can show them in CFA in the House Hold Pet class. But get them to the vet and first get them their first round of shots. And find out what sex they are. Keep us posted on these 2 cuties!
