What happened to the Jewish family pets that were left behind in World War II, Europe? Jewish families were torn from their homes, taken to ghettos and concentration camps. They were forced to leave their neighborhoods, livelihoods, possessions and the animals that loved and depended on them. Dogs and cats often faced bleak and harsh conditions, but faithfully guarded the house or farm. In the dangers and privations of war, they focused on comforting and protecting their people and when the family was taken away, they waited and watched for their return.
