Re homing two 3 year old neutered and spay cats

Brother and sister who love each but do not love my new dogs. They are too afraid to come out of the room and run into the dogs 😞 We have given it 6 months and it is not getting better. They are trying to use the roof as the door. We have a metal roof And when it is rainy they are slipping and almost falling off the roof. They need to be rehomed to a house that does not have dogs. The pic is a baby pic they are 3 now
