Guy Fawkes Night and garden bonfires kill hundreds of hedgehogs annually who shelter in prepared bonfires, with simple precautions preventing this.
Hedgehogs sheltering in bonfires that are lit suffer severe burn injuries, smoke inhalation and death. Individuals who survive initial burning face prolonged suffering from injuries that are extremely difficult to treat. The welfare harm from bonfire injuries is entirely preventable with a few seconds of care before lighting. This represents one of the most direct and simple welfare interventions available to any householder: the simple act of checking with a torch before lighting prevents individual animals from suffering a catastrophic welfare event.
