Linda --
Hope you've already started some of the "tub games" as have been suggested, here.
I have TWO boy Bengals who absolutely LOVE the water -- and my three girls aren't AS fond of it - but still do MUCH better in water than my DSH rescue cats.
You MUST go look at my blogspot. The cat's "Birthday Party" last weekend was a "fishing in the tub" party. I've got some pretty amazing photos of my boys playing in the water, one of the girls, "hovering" around the edges of the tub, almost standing on her head to reach the "toys" and even got my rescues interested

Good luck. Once they LOVE it -- it's hard to keep them OUT of it (fair warning)
