Oh yes, Pippa is a very skilled huntress - not that it's appreciated, and yes, she has a white spot on her tummy.

luckies4me! The mouse was dead when Pippa presented it. There's a field behind the garden where I suppose there are mice, but Pippa was very interested in a spot half way down the garden and we expect that's where she caught it. To me, the mouse looked very small, but I was told it was a full grown one - I'm a city girl and haven't seen a mouse since my childhood.

I don't know anything about the Hanta virus you mention, but I bet you can find some info on the net.
