The best type of flea treatment for cats is a modern flea medication that will interrupt the life cycle of the flea infestation.
We recommend the brand name Advantage flea treatment. It kills adult fleas before they are able to reproduce and lay more eggs, which is critical to the successful elimination of fleas.
Flea dips and shampoos will only kill the fleas that are on your cat at that time, but it will not do anything to prevent more fleas from jumping on your cat and then laying more flea eggs, to keep the life cycle going.
We recommend that you don’t waste your time with such things, but rather simply administer the flea medication, and your flea infestation will be eliminated in a short amount of time.
