A side result of Tabby's self-balding is hairballs. Hairballs are generally just a problem for the owner, who takes on the task of cleaning them up. The frequency of hairballs depends on the cat, the cat's length of hair, and whom she is grooming besides herself. Medication can be used if necessary. The Wicked Witch of the East isn't the only one who disdains water.
Cats are notorious for their aversion to getting wet.
If Tabby is older, however, and has never been exposed to water, you will probably not be able to change her mind about it. Cats can also be frustratingly peculiar about their drinking habits. Some will drink only from a certain dish, some cats insist upon running water, and some will only drink by dipping a paw into water and then licking it off. Drinking preferences, like their preferences for being wet, are set at an early age. Whatever Tabby's preferences, you need to ensure that she gets enough water, especially if she eats dry food.
