Flea collars
Quote from the Wired article.
"Imagine that, for a minute. And then go buy a flea collar."
How Do They Kill Fleas?
Conventional flea collars work by emitting toxic nerve gasses that are absorbed into your cat's skin. These gasses are also inhaled by your cat.
Some people feel that the use of toxic nerve gasses is a good enough reason not to use this option in their efforts to get rid of fleas.
Also, this method is rarely effective on its own. You will most certainly have to take other flea control measures to completely get rid of fleas and protect your cat from future flea infestations.
Since the collars alone are not very effective, the potential risks to your cat's health may outweigh any advantages to using collars containing chemical pesticides.
While they can be used as a part of your efforts to get rid of fleas, the potential risks to your cat's health and the fact that they are not very effective, make this flea control measure a less desirable option.

Lawsuit Filed Against Toxic Flea Collar Manufacturers
The Natural Resources Defense Council has filed a lawsuit against pet product retailers and manufacturers for selling toxic pet products that are harmful to both pets and human without proper warning labels.
The lawsuit alleges the flea collars leave toxic chemical residues that can cause cancer and neurological damage to children.
“Just because a product is sold in stores does not mean it is safe,” said Dr. Gina Solomon, a senior physician toxicologist. “Consumers have a right to know if a flea control product could make their pets or families sick.
In a recent study, the council found high levels of propoxur and tetrachlorvinphos (TCVP) on pet fur after using flea collars.
The lawsuit was filed against 16 manufacturers and retailers including PetCo and Petsmart.
