All that's left.

I toddled out into garden, yesterday, and chased a rather satisfied looking Moggy from the path.  VERY shortly afterwards I saw a pale patch in the grass.
Investigation yielded two wings, two legs and a pile of feathers.

Curiously, early today, I saw an advert(?) online, depicting an uncut patch of grass C/W wild flowers, and a neatly clipped lawn.  The gist of the message was the uncut one encouraged more wildlife.  The converse of the theorem? 
Had the lawn been neatly trimmed the Pigeon MIGHT have spotted the Moggy stalking it ?
