Many years ago, my partner and I used to have a roast chicken every Sunday evening and I had the bright idea of putting the carcass out on the back lawn to see if I could attract something interesting like a badger or fox.
Sure enough, every week the carcass would disappear shortly after I put it out on the lawn but whatever was taking it was, rather annoyingly, doing so when I wasn't peeping out of the window.
Eventually, however, my persistence paid off and one evening I was watching the carcass sitting on the lawn when, suddenly, from behind the garage came a cat.
It moved suddenly and swiftly and very much in the style of cats that one often sees in cartoons - its body almost hugging the ground, very little discernible leg movement and generally travelling as if it were on casters!
It darted out, picked up the chicken carcass in one bite and darted swiftly back to wherever it had come from behind the garage.
Oh well, it wasn't an exotic visitor like a fox or a badger but, on the positive side, she did become a little friend who remained for a long time. I honestly cannot remember how long she was with me but I'd be very surprised it wasn't 20 years - and she was an adult when she first arrived!
