Funny you know. I have rescued spiders and moths and other insects from cats, rodents - mice, shrews, voles, more than one rabbit - set the last one free this summer after giving it home for month or two till it was old enough, and whats a mole? from cats, frogs and toads have been put safe into a pond from the grasp of cats, rescued at least one tiny lizzard, Pip in particular has rescued all sorts of birds, not just cat victims but ill and young birds, I remember "Cassius crow" marching on parade on his wall and then flying off as well a seagull happily flying off towards the Great Orme (it was a beautiful sight seeing it go off from the hill we lived on mking its return to freedom) as well as the inevitable tragedies like the baby owl who we think was poisoned.
I have seen bats fly in the house, rescued pipistrelles mostly having been rescued, passed on to Pip set go back to their real world.
Some time this year, Pip and I dragged dead fox off the road, dark stretch where cars at night do (and I know it is not legal) travel at 80mph+ rather than see the pretty mature cubs go back to mum as they had when we passed and get splatted like mum - guess we risked the same fate ourselves.
I'm sure plenty of people have done and seen more but one doesn't have to be a Mudcatter to do it...
