What's the name of Rachel's cat in the American TV series "Friends"?

Mrs. Whiskerson is the cat Rachel owns in "The One With The Ball". Mrs. Whiskerson is a Sphynx, a rare breed of a cat that lacks coat. The cat, which costs Rachel $1,000, is reminiscent of her grandmother's similar cat with whom Rachel used to play as a child. Rachel's friends, however, are repulsed by the cat's visually unappealing look: Ross maintains that it is "inside out", Joey strongly dismisses its being a cat, Gunther is also unable to decide what creature Mrs. Whiskerson is and satirically asks Ross whether it is a snake, and Monica avoids the cat due to being allergic to them.
