Rats were the unlikely hero of a recent television documentary and a feature in The Economist magazine. They were shown helping locate unexploded bombs, and also being trained to recognise tubercolosis in laboratory tests. These are smart, social animals that make good pets, if properly handled. They are happy to be trained and owners say they are have a great sense of humour too. Compared to many small pets which prefer to stay burrowed away, or are nocturnal, rats are busy during the day time and are ready to play at any time. The charity involved with the vital business of training rats to clear landmines is APOPO and you can find out more details at this link.
