“Hero Rats” were my inspiration to start DangerRat Graphic T-Shirts here in Bellingham Wa. Rats are lightweight so they won’t set off the bombs. Hero Rats are Highly taken care of and Greatly respected. They put sunblock on their tails and nose and limit the amount of sun they get. They also see the veterinarian regularly and have a retirement program for the rats. When the rats’ olfactory(smelling) senses no longer work correctly they retire them to the visitors center as rat ambassadors, meeting the public and showing them how they find explosives through smell. It’s very cool, as are the rats 🙂.
