As the dark clouds of war drew closer towards the end of 1939, the HMSO produced the pamphlet "AIR RAID PRECAUTIONS FOR ANIMALS". It was a guide to looking after pets during raids. On the back of the pamphlet was an advert for the CASH Captive Bolt gun. Used by vets to kill animals. Prior to and in the beginning months of the war it is estimated over 7500,00 were killed by pet owners.
