hi
i was looking for articles on flea control spot on's and i found what i
think is a really good article and thought i would share it and i was
wondering if it was fairly accurate or not
for the acrobat file
http://www.apnm.org/publications/resources/fleachemfin.pdf
or
for the html file
http://216.239.41.104/search?q=cache:pJoMrA4DeOEJ:www.apnm.org/publications/reso
urces/fleachemfin.pdf+methoprene+dangers+cats&hl=en&lr=lang_en&ie=UTF-8


it pretty much says that all spot on's are not safe, even the ones you get
from the vet,  it was talking about dogs in the intro and it was in a dog
magazine though so i don't know if its was for all of them or what.  but it
pretty much tells you what is in the spot on's and what the results were
found in the lab test, and it says that fipronil and imidacloprid isn't any
better than methoprene and permethrin.

also according to 188petmeds.com the following medicatins contain what is
listed after them

frontline plus for cats contains Fipronil (9.8%), S-methoprene (11.8%),
Inert ingredients (78.4%)

frontline top spot Fipronil (9.7%), Inert ingredients (90.3%)

advantage Imidacloprid (9.1%), Inert ingredients (90.9%)

bio spot stripe-on flea control for cats Pyripoxyfen (5.3%), Inert
ingredients (94.7%)

and according to the article zodiac contains 45% permethrin, 3% methoprene,
52% not disclosed

and according to the article advantage has the same % of those things but
the MSDS sheet indicates there may be some solvents in it

also according to the article frontline plus is basically the same thing as
frontline top spot but it has 8.8% methoprene

and if you go to that article it tells you what they do,

so i awas just wondering if any of them are really safe to use, or are there
ones that are safer than others, becasue according to the article it scares
me even to use the ones you get from the vet

i meant that the percentages that the petmeds states are what the article
states as well, but the article also says that there may be solvents in
there as well
and not that it had the same % of ingredients that zodiac has

Laureli, this is purely anecdotal, so you can take it with a grain of salt if
you like. But just strictly from the experience of my own friends, people I
visit with at the shelter, and reading the newsgroup, I've never heard of
anyone's cat having a life-threatening reaction to Advantage or Frontline.
That's certainly not so with the OTC meds; I've heard horror stories not only
about Hartz but others as well. I did have a cat who had an allergic reaction
to Frontline; he drooled, panted and behaved as if the spot was burning badly.
I washed it off and he was fine after. He didn't react at all to Advantage.
(Incidentally, the other cats did fine with Frontline, and that's what they use
at the shelter)

And I didn't see anything about selamectin (Revolution) in the article. I've
done a lot of searches to find any potentially dangerous side effects of
selamectin, and have not found any.

IMO, you have to weigh all the factors if you are worried about using spot-on
treatments. If any of our current cats had flea allergies to the degree that
one of my previous cats did, there would be no question that I would be using
the most effective flea treatment available, because the potential long-term
risk (very slight, IMO) would be greatly outweighed by the need to alleviate
the cat's misery.

We currently use Revolution not for fleas but for heartworm prevention. IMO the
risk of heartworm also outweighs whatever small risk there may be longterm of
using Revolution part of each year. Our cats have had no side effects, and it
had the added bonus of getting rid of the ear mites infecting the stray we took
in.

My cats don't have fleas so I do not use any treatments.  However, if they were
to get them, I would probably go with a natural remedy first, depending on how
bad the infestation was.  I know these spot ons are supposed to be safe but I
prefer not using drugs on my cats unless they're really called for.  Here's a
link for treating fleas without chemicals:

Well, that's just plain wrong.  Here's a review written by Tina
Wismer, DVM, veterinary poison specialist at the ASPCA animal poison
control center.  It is a review of the active ingredients in most
veterinary insecticides, their MOAs and commentary on toxicity,
including references:

http://www.vspn.org/Library/misc/VSPN_M01289.htm

I was a molecular biologist working on insecticides (among other
things) for 15 years.  Fipronil and imidaclopid are two of the safest
insecticides to be put on the market, ever.  I have used Advantage on
kittens as young as four days old, with no ill effects.  I'd drink the
stuff to prove how harmless it is, if you wanted me to.  (And no, I
neither worked for Bayer nor Merial.)

I goota agree with you 100%.  We've used Advantage and Frontline on
literally thousands of cats and dogs in my shelter and never had a problem.

I think Advantage and Frontline are available without a prescription.  We've
bought both in bulk quantities directly from the supplier and I don't
remember sending a prescription or asking our vets to send one.

Just as a side note, you will also notice that the article you cited
does not include published research reports as sources.  Without
published references, such a review is simply not believable.

You have nothing to be afraid of, when it comes to Advantage,
Frontline or Revolution.  Some animals will have a localized reaction
to the carriers (solvents) used in the products, but such reactions
are not common.

hi
thanks for the information, i'm going to phone around on monday and see if
any will give me some without an appointment, if not i may take one of my
pets to the vet and then asked for like a 6 months supply and then use it on
my other pets.  how would you go about splitting up a dog tube?  i figure
get the dog stuff that way i can put it on both the cats and dogs, and then
i can get a dog lisence and take one of my dogs to training since i get it
free at my work, she won't listen and stop stealing food and running away
when she moves the boards that are between the fence and the ground to keep
her in.

They sell it at PetCo and PetSamrt.  You can also buy oit on-line at
1-800-petmeds, or other sites.  You do not need a prescription.

Advantage dosage is is 0.8ml per 10lbs of cat.  The largest dog dosage
contains 4ml total, so each 10-12 lb cat can have 1/4 of the total
amount, which would be 1ml. The "extra" 0.2ml isn't likely to be a
problem, especially if your cats weigh 12lbs or more. If they weigh
over 20lbs, they need 2ml.   You will need a syringe (sans needle) to
apply the dosage.

And FTR, 1cc = 1ml.

If you need dog dosages, they are available on the web.  Just Yahoo or
Google the terms: "Advantage" "fleas" "dosage" and "dog" or "canine".

If you need help figuring it out, just ask.

hi
thanks for the reply but i'm in Canada and I've looked at petsmart and they
only sell hartz and zodiac.  also i phoned my vet about them and they said
that i need to bring the animals in to get flea treatment since it's
prescription according to the lady on the phone, i'm not sure if the laws
are different here.  i'm going to check a few pet stores though and see if
any of them sell it, i don't think so though.  it seems really horrible if
you can only get it by a vet that the government would allow hartz to be on
store shelves but not the good stuff.  i also might phone my normal vet
again and see if they will give me the stuff for my kittens who she saw 2
weeks ago, i've just been busy with school and work and next week i have off
of school.
