I think they’re actually very nice. Wouldn’t want them in the house though. I had one living in a huge pile of rubble outside my back door once. It was in the winter and I became aware of it after hearing strange noises at the back door at night for about a week. I finally noticed that something had chewed a huge hole through the wooden weather board at the bottom of the back door. In the spring we filled two skips with the rubble - after nearly a mornings work, down to the last couple of barrow fulls, Mr Rat jumped off my mates shovel and scampered off. He was the size of a rabbit!
