Okay.

First dedicate 45 minutes to 1 hour a day to training.  You will also
need one of these cat wands.  Preferably with the shorter feathers, or
ribbons.  You can find them at almost any pet shop.

Playtime starts with kitten that's just been weaned by it's mother.
Playtime always takes place in the bathtub.  Always be very careful not
to exceed the body temperature of your cat, so keep an aquarium
thermometer in the tub.

Week 1, just keep the water dripping, never allow it to run, and keep
the drain open.  If the cat jumps out, don't put it back in the tub,
lure it back in with the wand.  Make sure it can get in and out by
using an well anchored towel as a two way street at the opposite end of
the tub from the drain and dripping water.  The wand likes water, and
if the kitty is gonna get close, it constantly has to head for the
dripping faucet.  Lead it into getting it's face wet as many times as
possible, and never be mean, or forceful.  Let the cat decide when or
if it's going to attack or not, or get wet in the process.  You will
see it will be cautious of the water, immediatly react to it at first,
even jump back, or run right out of the tub after one drop.  By the end
of the first week, the cat should be getting quite wet.

Week 2, keep the dripping faucet a dripping faucet, but now plug the
drain, and when the puddle gets big enough for the cat to jump out of
the tub, let the water out and start again until you've reached the end
of an hour.

Week 3,  continue the same process and see how deep the water can get.
At that point ripples and wave will become toys.  Keep allowing the tub
to fill, and allow it to get used to slow trickling water.  By the end
of this week your cat should be swimming at one end of the tub, and
jumping in and out to play.

Do tell us -

-- we need to know this.
That's something I can live without. Our kitten has no fear as it is, make
him the kitten from hell?
