This shit makes me laugh every time.

I know times are tough... but the OTC DOES NOT WORRRRRRRRRRRRRK. And most likely, the sores on their heads are a reaction from the shitty products you buy. The general public is fooled into believing this stuff is safe and works... it doesn't. I have seen more OTC flea product reactions than any other toxicity or allergic reaction in cats and dogs. Adam's, HARTZ, Zodiac, Biospot, etc... all are fucking garbage.

The BEST you can do is at least a bath a day with a bar of Dove soap. It suffocates the fleas. Isolate the cats in a laundry room or bath room. Vacuum the shit out of your house... possibly shampoo the rugs. Before you vacuum, sprinkle Borax 45 mule powder all over the carpets and upholstry. Let it sit for 24 hours. There is an ingredient in that which pretty much dissolves the exoskeleton of fleas... then vacuum it up.

If you had money, I'd say buy Capstar online, along with Advantage or Frontline... but that can get expensive. Capstar is a pill you give them which kills 99% of fleas on cats within 6 hours. On dogs... 4 hours.

Another tip is to not let them outside. ;)
