Cat vs Squirrel - who wins?

[hal]

I had a gigantic cat - he was a stud - always top dog - never had to defend his territory - he was too big...

I once saw him stalking a squirrel... after a moment or two, he pounced. The squirrel started bolting up a tree, but 4 feet up, stopped, turned and hissed in a VERy serious tone.

Stopped my cat in his tracks - he turned around an jumped off the tree without looking back...

I'm sure he could have taken that squirrel, but it's clear that the squirrel was ready to fight to the death - my cat wasn't...
