[The Witcher] How are the other Witcher schools doing?

I know  A big point of the books and games is that the secrets of making new Witchers have been lost due to an angry mob. However that's just for the Wolf School correct? is it possible the other Witcher schools have survived and retain the knowledge of making new Witchers? Or did they all get knocked out at once? (I know in the 2nd game there is talk of reviving the Viper School)

They all suffered from similar problems to the Wolf School: as their numbers dwindled, the ones that knew how perform the Trails either died or refuse to do so. That being said, we don't really know the statuses of the other schools outside of Wolf, Viper, and Bear. It's possible that the Cat School is still creating Witchers, and may even be possible to revive the Wolf School as the Cat School were originally made of "failed" Wolf School Witchers.
