I would suggest this if your cat has never had fleas and you just happen to see one or 2 on them. My indoor cat randomly had one on her so I bathed her with this and I found the flea dead in the tub. I haven't seen any on her ever since. It doesn't foam up and the scent is very strong so rinse very well. I actually just add a few drops of this in my cats bathing water as a rinse after using regular cat soap. The cedar oil doesn't seem to bother my cat but i didn't use much of the soap because like I said she didn't have much fleas. I recommend this as a special bath soap to use occasionally if your cat hasn't really had a flea problem.
