24 hours after treatment cat lathargic, anorexic and diarreah. He has been poorley for a week. I took him to the vet and he had a raised temperature of 1 degree. Vet just gave him an anti inflamatory and said it was just a virus.

I've been using Advantage 2 on both my dog and cats. Yes, it was applied correctly. I have watched the video, it was in the correct spot, directly on the skin. I vacuumed and pulled everything apart (multiple times) to do so, washed all pet bedding and blankets....and sprayed my house. I reapplied every few weeks for a few months. They still had so many fleas! What a waste of money! This is two years in a row I spent hundreds of dollars on Advantage 2, used it over several months, to end up resorting to flea baths and the Zodiak spray (with instant results) that cost about $60. This for all of my animals for the entire season.

I applied the Advantage to my cats as I have many times before. This time, within hours, several of them were salivating, convulsing and having respiratory difficulties. It resulted in 9 out of 10 of them going to the emergency vet within a 3 hr to 36 hour period. One passed. I have incurred over $8,000 in emergency vet charges and hospital bills due to this. Stay Away!!!!

Bought large cat dose, purple type. She's had 2 doses in 5 weeks & still has flees. It simply doesn't work on her.

Every since I place this product on my cat, my kitty wasn’t the same vomiting, foaming from the mouth seem depress dihrea hiding etc . my vet. Gave him antibiotics and meds for nausea he seem to be fine but then started to get sicker now has passed . Please!!!! EVERYONE be sure of doing your research on these flea products before placing on your baby, bc Im sick to my stomach knowing I’m his care taker / his mum and I thought I was doing the right thing turns out I wasn’t . Now my pooka is gone .

Although my cats had no negative reaction to this product, it doesn't work AT ALL. I bought a few of the 6 pack Advantage for cats over 9 lbs. I've been putting it on them every week and they still have fleas.I am a clean person. I've been vacuuming daily, washing blankets, bedding,and towels constantly, and brushing the cats about every 2-3 days.This product does not work.I'm extremely unhappy because I spent 160$ on it, thinking I'd have about a years supply but I'm almost out. I will not be buying more of this specific product and would suggest you don't waste your money.

Bought 6mo. supply of advII large cat (13yo healthy 13lb cat). 1st dose, 2 days later cat acting strange not eating/drinking lethargic. Vet tests inconvlusive $500 hole in pocket. Didn't think anything about flea med causing her behavior. She gets better. 2nd dose a month and 1/2 later. Same symptoms appear, but worse. Added confusion/uncoordination/vomiting. Vet visit again. Conclusion, organ failure due to poisioning. this product, these heartless, and any company selling their product. A call to them will result in their denial and getting hung up on. There's a special place in Hell for these and anyone like em.

This is great for my cat enjoy giving it to my cat my cat loves this product would not say a bad thing about this cat product

This actually worked really well for my cat up until a couple of months ago. I live in a unit and two of my neighbors use this also. Seems the fleas have built up an immunity to it though which I expected would happen after awhile. Will definitely go back to using it soon, hopefully by then it will work against our fleas again. Didn't affect my fur baby at all, he doesn't like the smell though as it is quite strong. As for all the negative reviews IT IS POISONOUS! DON'T LET YOUR CAT LICK IT!

Was working fine until one month there was a bald patch and burn like mark. It ended up becoming infected so we took him to the vet. He was given antibiotics. Will try flea collar as comfortis tablets are too big and the whole process is too difficult and protracted getting him to swallow the tablet.

I had high hopes. My house was not infected, just noticed some flea dirt. After putting the application on, i started to see fleas on surfaces, but not quite dead. I thought it was working..but 3 weeks later we still have fleas and they are no longer dying. Just like frontline, this product no longer works. Will be switching to pills instead.

Used frontline for weeks to clear up a bad flea infestation which got worse dad by day. Changed to advantage and fleas are gone. Couldn't recommend this product enough.

This product worked quickly on my cat Molly, there were no side effects to it and easy to use. She has not shown signs of any fleas after using it a month ago.

Reduced number of fleas but had to buy another product in two weeks. I was disappointed that I had to spend another $50.
