I have a couple of questions about my cat Sapphie. She has now been on black walnut, wormwood, and clove capsule for a week. Will this kill any parasites in her? Should I be seeing them come out of her? Does she need to be on the Humaworm for pets, as well? Also is there any recommendations for flea control that is not toxic? I am hestitant to give her Advantage. Any information is appreciated.
