Why do you need to bathe her? Cats do a good job of grooming themselves. But if she has fleas or is really dirty, I'd give her a bath with a pet-friendly shampoo.
Since shampoo appears to be optional here, I'm assuming you're just trying to freshen her up and not clean up poo out of her fur or anything like that? Unless she really needs a bath with a good scrubbing for something she can't clean out of her fur on her own, you might try some waterless shampoo or between-bath wipes. They won't make her sick and they're a quick way to make her seem "cleaner" without having to put her through the stress of a bath.
