Flea Free Cats

I'm particularly interested in the brewer's yeast method where you directly rub it on the cat's fur. The other methods you have written seem to require a lot of work though. Should be easy enough to find yeast in the market.

A friend of my sister recommended rubbing gin on cat's furs which stun the fleas but does not get rid of them. An immediate bath is required to easily get rid of the stunned fleas and eliminate the possibility of the gin being ingested by the cat.
