Has anybody else's pet had a bad reaction to Frontline Gold?

[Number9Dream]

We have been using Frontline Plus on our cats for years. All of our Siamese have been leash trained, and love to take walks around our yard. We'd split an ampule between two cats, and then keep them apart for more than twelve hours so that they wouldn't lick it off each other. We never had any bad reactions. Last Sunday, we split an ampule of Frontline Gold (so they were getting half of a dose), between our 3 y/o female, Emily, and our 4 y/o male, Zack. They were separated as described above. On Monday Emily stopped eating (and she's rarely finicky). She still wasn't eating on Tuesday and had thrown up a couple of times. We attributed it to the Frontline when we read on the box that one of the side effects was nausea. Zack showed no ill effects. We attempted to wash off any remaining Frontline. Long story short, she went to the vet 3 times last week... got 2 Normosol infusions, 2 anti-nausea shots and a couple of anti-pain shots. When she still wasn't eating on Friday, our vet gave her a steroid shot as a last resort. By 5:30pm, she began to eat normally again, and has been fine since. Our vet noticed that an additional insecticide has been added to Frontline Gold (compared to Frontline Plus), and he phoned the makers of Frontline. The person he spoke to, though denying responsibility, said Frontline opened a case file and would pay a portion of our vet bills. We'll never use Frontline Gold again.
Was wondering if any DUers have had similar experiences.

4. So sorry to hear this. This year is turning out to be terrible for ticks, fleas, and mosquitoes

here in Georgia. Have never used Frontline Gold, but have used Frontline Plus recently and one of my cats--10 yr. old tuxie, is currently under vet care/observation for a malady of unknown origin/etiology. She still has a great appetite, but is losing weight and acts like an invalid. She was healthy, frisky, full of spark until mid May. Now, she acts like she is failing. It is tearing me apart.

Normally, I use Advantage Multi or Revolution because of the ticks, mosquitoes, etc. and I have some on-hand now, but thought that it was early enough in the season that I could get by with just flea/tick preventative. I bought it at the pet store vs. Advantage/Revolution that I buy from the vet.

I hope you find out what is going on with your Emily (know how you love your kitties.) I hate putting these chemicals on them, but that is what we deal with in the SE US. I have gotten ticks already this year from going out to hang clothes on the line. I am using Lemon Eucalyptus spray on body, but have picked Lone Star ticks off myself and one (half-wild) cat that spends a lot of time outside. I don't know the solution.

5. Hi Japple. Best wishes for your tuxie kitty.

Many here are aware of the generous work you do for our furry friends, and are sending good karma in your direction.

Emily has been back to normal for 4 days now. She's going to be fine. The steroid shot worked great (don't care why). I'll keep you posted if I hear from the Frontline company.

6. Hey #9! So happy to hear that Emily has returned to normal. My girl is going back to

the vet on Friday for x-rays. After reading about topical flea applications online, I am beginning to suspect that might be what started her decline. I couldn't believe that could cause it, because none of my other cats have had a reaction. Will need to discuss this with my vets.
