Reply #6: I think your cats have fleas and that you really need to do something [View All]

before you have a household infestation. At this point, I would be more worried about them being eaten alive by fleas than their exposure to toxic chemicals. The fast movement is the flea crawling on the cats. The brown grainy stuff is flea dirt. If you can get some Advantage, Revolution, or Frontline, apply that and see if their scratching stops. You said they are indoor cats, but the fleas can come in on your shoes or, in the right zone, hop right in through cracks in foundation, door seals, etc.

Diatomaceous earth (DE) can remove the fleas from your carpet and is a natural substance. Sprinkle it on the carpet, let it sit for awhile, then vacuum. You can google it and get more information and further directions.

Do you have someone who can help you put the flea treatment on your cats, then treat the floors/carpets. You really need to address this soon. Good luck, and keep us posted.

Edit to add: I see from your profile that you are in Florida, which is the flea capital of the world. I hope you can get someone to help.
