This product contains the EXACT same ingredients as Frontline except
that it doesn't contain fipronil which is what kills the fleas. It
contains Precor and less than what's in Frontline. So if you're
telling me that this product isn't safe then Frontline sure as heck
isn't safe either.
Just because it's an over-the-counter product it doesn't mean that
it's not safe. You just have to read the ingredients and know what's
safe and what isn't. I listed the ingredients in the product I was
talking about on my first post. Assuming that all over-the-counter
flea products aren't safe is like discrimination or something.
That alright though, I contacted the veterinarian and he said it was
ok to use.

And about the powder/spray. I was planning on putting my cats in the
basement for several hours so they wouldn't have to inhale that. The
vet said that a good idea. And the basement is fixed up real nice and
they like it down there anyway so don't worry about that.

Perhaps I asked my original question incorrectly. What I should have
said is: Is using a veterinarian, EPA, etc. etc. approved Insect
Growth Regulator (IGR) on my cats and combing them everyday with a
flea comb a good enough flea control for a minor infestation?
