To Michelle Skinner - There are slight variations in pH between animal's and people's skin, but it is not very much. I know of a lot of people who use human shampoo on thier pets (when fleas are not a problem) with no ill effects. But remember - no two people bathe their pets alike - most vary the length of time, amount of shampoo, the length of time shampoo is left on, frequency of bathing - the variables are enormous. If you have a flea problem, you need a flea shampoo. Human shampoos (we do often use baby shampoos on our ferrets between flea baths) can be used in some cases. For best bets, a pyrethrin based shampoo that can be used on kittens is the best choice for most pets.
