Default Re: Waking up at strange times in the last two days?

If its highish pitched and undulating it could well be a cat scare device.

Search your neighbours gardens for a green box, especially the old fogeys houses. Old people cannot hear that frequency and do not realise the hell that they are putting their neighbours (and cats) through when they stick these devices on their lawns.

In fact on a calm day, I can hear one of these devices 100 yards away.
