Hi Jane, the Wessex FC has been testing since 1990 and we do not allow ferrets to attend our shows unless they have a neg. test certificate. We have tested ferrets from all over the UK and it seems that around 10% of all ferrets we tested carry the Aleutian virus. Chris Lloyd ICQ no. 44575318 Wessex Ferret Club.
