Evening Ditchy, just picked up this thread sounds like a good crack, one thing confuses me though, all the pictures so far are Rattus Norvegicus not as you mentioned earlier Rattus Rattus , if you guys are running around rearing pens , tips etc killing Rattus Rattus (Black rats) i think the ministry might like a word, Something to do with black death and plague , i know i am being pedantic, but according to a boring lecture i attended a short while ago Rattus Rattus is only found in a few places such as Bristol, Liverpool and London docks, and being very cloesly monitored.
