I live near the railway line and often see a number of foxes (three together, one night) running around the streets. There have been a number of cat disappearances in my area recently. These two facts may not be entirely unrelated.
I like to see the foxes (even though they may be killing cats). I like to see squirrels, magpies, crows, robins and wood pigeons. I like to see ladybirds and even the occasional spider.
I am not quite so happy to see a mouse in my kitchen.
