I've witnessed a stand-off in my back garden between a squirrel and one of next door's cats.
I would have thought the cat would have attacked the squirrel, but once the squirrel turned
its back to the cat and started to raise and waggle its tail, the cat became scared or confused
and decided to stay motionless, as the squirrel slowly made its escape.
(If only I could have got the video on my phone working quickly enough to film the encounter.
I knew they would confront each other at some stage).
