Terrassa, a town in Catalonia, has temporarily banned the adoption of black cats from shelters from October 6 to November 10 to prevent potential harm during Halloween. This decision, made by the local animal welfare service, aims to protect the cats from being used in rituals. Although there have been no reported cases of cruelty in Terrassa, the council is taking precautions due to warnings from animal welfare groups. The ban is described as temporary and exceptional, with exceptions assessed individually.
