Thanks, Siamcat. Maybe just as well. One of mine attached himself to the throat of a German Shepherd, and just hung there and swung there. The owner wasn't best pleased. I was sorry for the dog, though.
Another one was a terrible thief, and used to bring in brushes and things like that. It would have been a bit daft to go knocking on doors to see if someone had lost a brush, so I just kept it. Sadly, when bringing home a trophy, he couldn't differentiate between a juicy rabbit and a fat rat.
I'd better sign off now because I could haver on all night.
