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. http://www.samyu.com.tw/ePETS/pages/P15-Cat%20Toys.htm
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.
