From the web site........

ProMeris Duo is the only product available from a veterinarian that contains the active flea control ingredient, metaflumizone.
This new compound features an exclusive mode of action that attacks fleas’ nervous system by blocking neuronal sodium channels, which results in paralysis and death of the flea.
Metaflumizone has never before been used to control fleas and research shows they are readily susceptible.
Metaflumizone is proven to control 2 flea species (Ctenocephalides canis and C. felis) and protect against re-infestation for up to six weeks in dogs.
ProMeris Duo for dogs can be used as part of a treatment strategy for flea allergy dermatitis.

It was on My bengals list. that's really all i know.

That is what I was wondering too.  Isn't this stuff new on the market?  I remember seeing a TV ad for it recently.  To be honest, I don't use any "normal" flea or tick products on any of my pets.  For me, I just like don't like the idea of putting something that is poison on them.  I have used the herbal repellents on Daisy and have never had problems with fleas or ticks.

In my opinion, killing fleas in a petri dish is WAAAY different from applying to a living being..........

In the mid 80s, we found our second kitty.  I didn't know any better and put a h a r t z flea collar on the poor guy. I couldn't understand why he kept removing it himself.  He knew better than I did.  Now I know that he was having a reaction to it.  Thank goodness he taught me and I stopped putting flea collars on him and he recovered from that and went on to live many years.   

I had to put one dose of flea drops on Cassi (kitten) when I brought her home since she was loaded with fleas.    

This is a new product designed to be a more effective product than?other flea/tick treatments that was just released this year. It is available thru a vet and not currently on-line. I got ProMeris this week for my 7??dogs (6 Huskies & 1 Golden-Airedale) , and the results were?debilitating for nearly all of them-including me. Since my incident this week, my?vet has pulled it from distribution and alerted the manufacturer, Fort?Dodge .

Here are my results: Within less than 2 hours after applying, 4 of? ?my dogs had vomited from 2-4 times, 3 were disoriented and stumbling, 1 was dragging his back leg, 1 was salivating. I had very similar symptoms??like?an allergic reaction-my lips were swollen, eyes very red, mucous??membranes such as eyes, nose, and mouth were stinging. I was very disoriented-dizzy equilibrium and not able to drive. To make this a short story-all 7?of my dogs were admitted to the hospital for veterinarian care, and 3 of them remained for care, IV fluids and observation for 24 hours. I was in the emergency room. I'm home now and so are the dogs. We're all feeling?much better. Vet bills were over $2,500 and Fort Dodge is paying for?these. Not only can the product cause this reaction, it has a highly noxious odor that permeated the house and is just starting to dissipate after 3?days.

Your dogs/cats might not have the same reaction, but given my?experience-I wanted to help you all become well-educated about the product.

     You beat me to it!     I was just about to check Snopes when I saw your post.  I am always skeptical when receiving an e-mail regarding a product being bad or some other danger such as that.  We'll see what Snopes discovers about this - have a feeling that it is just another hoax.
