Allerpet Cat Dander Remover, 12 oz

Does this work well on clothes/fabrics that a cat may have been around? Or just for the cat's physical body?

Is regular bathing required when also using this product regularly?

How much do you need to clean one cat once? How long would one bottle last I guess is another way of asking the same question.

what are the ingredients? (preferably a picture of back of the bottle)?
