Is it safe to bathe older cats and 6 month old kittens with Johnson Johnson's Baby Shampoo?

Is it safe to bathe older cats and 6 month old kittens with Johnson Johnson's Baby Shampoo? They have fleas , and I just wanted to be sure. Because I've read articles that it was safe with just a little bit of the Johnson Johnson's baby shampoo, and that it would get rid of fleas just like tiny tigers kitten shampoo.
