It's the volts that jolts, but the mills (mils?) that kills.

12 volts IS enough to kill, if the contact is near-perfect, so
the whole voltage goes across the heart's control organ, but it
is extremely rare for it to occur.

While that is true, most things like portable fluorescent lights
and battery-powered electric fences include a DC to AC convertor,
so that the voltage can be transformed up.

There is, as smoothing is never perfect, but it should be small
(to avoid battery damage). Another (very likely) possibility is
that the charger was defective, and the mains supply leaked to
the output.

One of my friends cat has his tail chopped off. Luckily beaver was
saved by the local vet but he was never the same friendly beast again.
Never went anywhere near you if he did`nt know you.

I think it`s fairly safe to say that we all have some local account of
some idiot who has been cruel to the animals we love and care for.
Seems to me that its on the increase too.

You can get these transformers that allow you to use 240V AC equipment (game
machines, DVDs etc.) through the cigarette lighter socket of a car!

Would this be enough to kill a cat with 12 Volts?

These are "inverters" not transformers. However by switching 12v dc
through a coil you can produce very high voltages - as in your car
ignition system.
