The other day, when I looked out of the window, there were three cats and a fox sitting in a line across the meadow, all staring intently at mouse holes.
Of course, when I opened the window to photograph the scene, the fox got nervous and wandered off.

I managed to take these pics of him (making presumptions again).



Today I spied him at another mouse hole.
I am incapable of opening windows silently, it would seem, so when I opened the window to photograph, he (or she, as the case may be) trotted off a few paces, turned to see what the noise had been, then sat down and watched me for a while before leaving the scene:




Now it is chasing crows!
Rabies?
