Fleas are one of the most successful parasites on Earth, so they're a problem in many temperate climates. With over 2,500 species, it's no surprise than many of them want to feed on our feline friends. Dex P. writes:
Dex, we don't particularly care for any of the commercially available topical flea treatments because the chemicals used often have side effects, some of which can be disastrous for individual cats. There's just no way to know who will have a reaction and who won't.
We recommend a more organic approach. Organic flea control is best achieved when the little nasties are attacked on multiple fronts.
First, you should make sure all the cats are healthy and are being fed a species-appropriate diet. Given a choice, fleas will be drawn to the least healthy hosts. See our top food recommendations here.
Next, use a flea comb to go through your cats' fur on a regular basis. To be most effective, slowly run the comb through their fur and then dip it into a glass of soapy water to clear it. If you find fleas, they'll end up in the water which you can then flush away.
Finally, use a deterrent product like food grade diatomaceous earth or cedar oil directly on your cats' fur. Massage it in and, in the case of DE, avoid dusting it to make sure that kitty won't breathe it in. These all-natural products will kill fleas and keep them away but will need repeat applications to remain effective. You can also use a little diatomaceous earth as a barrier for other insects at entryways and under baseboards.
Dex, we're confident that the organic approach can be just as effective as the chemical bombardment method, but it does take diligence and works best before a major infestation takes place. We wish you and your cats all the best!
