Natural flea remedies you might read about:
Garlic- As mentioned above, not to be given to cats or kittens. I have actually put this to the test with my own pet, a Labrador Retriever named Phoebe, and it did not work. After checking with the Vet to find out if Labs have a sensitivity to garlic (they don't), I began to add it into her diet. Since she routinely plays alongside the fence with neighbor dogs fleas are always a threat. During this experiment, she began to have fleas despite the garlic. I would use diatomaceous earth to kill the fleas on her body, and in a few days the fleas would be back. I had to conclude that the garlic was not working. I should point out that I did not know the correct dose of garlic for a 70 pound dog, and I only fed her garlic for a few weeks, longer may have yielded better results. I point out though, these are the same problems you will face if you decide to use this method. UNDER NO CIRCUMSTANCE DO I SUGGEST YOU FEED RAW GARLIC TO YOUR PET.
Essential Oils-The theory here is that the smell of concentrated oils from various sources will repel fleas. This may be true, but pets may have difficulty metabolizing essential oils, resulting in a build up of toxins stored in the body. This often results in the death of the pet at sometime in the future from "unknown" causes. In other words essential oils can keep your pet free of fleas right up until it kills them. Cats and kittens especially should avoid essential oils because they have a very difficult metabolizing them.
Bakers Yeast-This one, I have to profess, I do not have a definitive answer for. Many people give it to their pet, often along with garlic, mentioned above. I will hold an open mind until I get a better handle on this remedy.
Making a lemon based spritz to spray on your pet.-This does appear to work as a repellant. There are variations of these remedies with various citrus fruits. There are various recipes out there but essentially you take a couple of lemons, slice them up and boil them in pot of water. Boil for a while, then turn it off and let it sit and steep until the next day. You then strain out the liquid and use it in a spray bottle to spray your pet. This makes your pet smell like a lemon tree, but does appear to work from the people I have talked to about it. I have two problems with this method. I do not want my dog to smell like lemonade and if you make it too strong, you have created lemon essential oil which might be fatal to your cat. And good luck finding your pet when you pick up that spray bottle the second time.
There are two clear choices for safe natural flea remedies. Food Grade Diatomaceous Earth and boric acid (Borax). Food Grade Diatomaceous earth is the clear winner, only because Borax can have an adverse effect on humans and animals under certian conditions and will bleach out colors if you are not careful when using it on carpets. FGDE does not share these hazards.
