I recently adopted a stray and gave him a dose of some flea medication. He is always outside. I don't like the idea of using a "pesticide" but will if I have too. I have 2 other indoor cats and have niticed them scratching lately. I have heard that garlic works well, but have no idea...garlic powder, raw, or what ever. Anyone else use this method or something else organic as a flea repellent?
