Advantage for Cats

Advantage flea treatment now made by elanco – Used to work well when made by bayer & bayer, probably the best non prescription treatment. The newer elanco version simply doesn't work well enough, having to reapply within 2 weeks.

GAVE MY CAT A MISCARRIAGE!!! – DO NOT USE ON PREGNANT QUEENS!!! NOT SAFE - DONT RISK IT!! This product killed my cats unborn kittens within a couple of hours after giving it to her!! I’m absolutely shattered to say the least… I’m a registered cat breeder of 15 years, so I know what I’m doing. My Vet confirmed this is what caused my cats very sudden miscarriage. Not only that,… Read more

but it left a huge burn mark on my cats neck where it was put on. 7 dead Maine Coon kittens, thanks very much!!!

I will never use this product again, I will be going back to using MILBEMAX!!!

PLEASE DO NOT USE THIS PRODUCT!!!

4 week kitten until 14 weeks – Got kitten at 4 weeks infested with fleas on its face, around neck first treatment lasted 2 weeks due to bathing cat for faeces on fur (kittens cant clean this). Gave 2nd treatment, fleas gone. Forgot treating until 14 weeks old fleas reappear, one caution; not put oil on shoulder they can lick, put deep in fur at the base of the skull. Show details

Works Great – After Frontline stopped working on my allergic to flea bites cat, I tried a couple of the other spot-ons before Advantage. Unlike the others, this one worked a treat. Within a day he'd stopped trying to scratch and lick his skin off, and in a week or so I noticed the areas of skin he'd chewed raw had healed and the fur start to grow back. I've… Read more

kept him on Advantage purple for 4 or 5 years now. It still works fine and I'm happy to pay a bit more for the peace of mind that the fleas are kept off him and he no longer suffers with irritation.

I put the stuff on the back of his head, just above where it meets the neck, as I found he managed to lick too much off if I put it between the shoulder blades. That ensures the maximum benefits. I'm very happy that not only does this stuff work, but it works very well.

Very effective – 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.

It’s not the same as it used to be. Completely useless – This isn’t the same product it once was. I have used this on all my pets for years & it worked well, however it’s no longer the same it’s pretty much useless I have applied 2 treatments on my cat this month and he is covered still in fleas. I have noticed the product has been slowly failing over the last year I will be calling the company today to complain Show details

It does not work – I have two cats two weeks ago i put a vial each on them, they are still scratching, have had to put another vial each on them days ago , they are still scratching, i paid $52, waste of money, from Pet Circle

Think Big Pharma Doesn't Apply to Pets? Think Again – I’ve applied my second monthly treatment to my cat and he still has fleas. IT DOES NOT WORK! Further to this I’ve just read some of the comments below and am shocked and disgusted that this poison is still on the market and being recommended by vets when it is clearly harming and killing peoples’ beloved pets. I can't believe this… Read more

pharmaceutical corporation will not even issue a women a REFUND - they should be sued till they're out of business! Think Big Pharma doesn’t apply to pets? Think again.

Do Not Use – After using Frontline for years I thought I would have a change. So bought Advantage and after giving it to my cats they became ill, foaming at the mouth and lethargic. I quickly washed off with mild soapy water. Do not give this to your cats it’s toxic. Show details

Worst thing I ever did – My cat has today died I put this product for the first time on my cat within hours she was walking and collapsing her breathing became very deep , had a vet visit with her age 15 they said her heart was very bad not the product, but my cat was playing with my little girl fine before I put this on her , I know this caused this  Show details

Awful skin irritation and fur loss months later – I applied Advantage flea treatment to my large cat. He doesn’t usually need these treatments so it was his first application in about 5 years. Two months later he is still scratching at the application site with scabs and missing fur with the bald patch growing. This stuff is POISON- don’t put it on your animals. I deeply regret it. Show details

Crap does not work – We bought advantageII This crap does not work!!!! used three viles on my cat within a month and guess what he STILL has fleas , since this site won't let me give no stars i have to give it one which it does NOT deserves.......save your money i paid over 50 bucks for mine , buy the cheap pet store brand at least it works Show details

Does not work – This product does not work after adhering to the strict instructions to a tee my 17 week kitten has had her 3 treatments of this and she still has fleas, disgusted as this product is not cheap don't use it a waste of money Show details

made my cat very sick – 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. Show details

Did absolutely nothing – I bought this and the one for large dogs. Neither worked! $180 for nothing. Extremely disappointed as it offered no relief to my pets. Do not recommend at all! Waste of money. Show details

DOES NOT WORK! – 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… Read more

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.

9 out of 10 cats ended up in emergency hospital....one died from Advantage – 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!!!! Show details

Horrible Product, Horrible Bayer Customer Service – This crap does not work. Call customer service about it, and all you'll get is a bunch of condescending lectures about the flea life cycle. Then they blame you for not vacuuming enough, etc etc. Hmmm... Well let's see... I ****removed*** my cat from the environment and moved into a new house which is completely flea free, and the crap still… Read more

doesn't work. So their stated theory (lies) that it's the environment is a load of baloney. Fleas are not dying, in fact seem to be getting stronger and bigger. These pharmaceutical companies may as well be politicians with all the stories they spin. And they are as rude and obnoxious as they come. Totally agree with the other person who said they got hung up on etc. So did I. And now I find out this garbage is actually killing cats. When do these pharma jerks ever get held accountable?? Never. And on another note~ notice bayer is putting cancer causing ***talc*** is their aspirin. Not taking that anymore either. How the hell do these heartless jerks sleep at night.

Please be careful with older cats – I have used flea medicine for my cats through the years so I really was not concerned when I ordered it again since my cat was spending some time outdoors and my husband had been bitten by something. My cat was 17 years old and she was doing quite well for her age, climbing onto the bed, drinking lots of water and eating well. I was traveling… Read more

and ordered the medicine and my husband administered it. But I was heartbroken when about 3 weeks later she became very ill and the vet told me she was in renal failure. It can only have been the dose. I feel her body was not strong enough to handle it. I should have checked with my doctor before administering it. I am writing this in case your cat is older, please make sure he or she can handle the flea medication before administering. I miss my little kitty very much because I almost got a chance to share some more pleasure moments with her. But in her honor, I am letting you know so you take proper precautions as needed. Love from Ginger Sophia.

Packets were empty when opened – If $$$$ packet only 2 were full others were empty. I returned it to the vet. They said it’s such a small dosage you probably see it when administered - but I know they were empty. Show details

My heart is broken, I believe this product killed my kitty – 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… Read more

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 .

Beware of this product – After using this spot on treatment from the vets for my cat, putting it in the place suggested by the pack, he became ill within hours, stopped eating and drinking and became extremely lethargic, not moving for a day from the sofa and not even wanting to go out or even going to the litter tray. Took the measure of squirting water into his mouth… Read more

using a plastic syringe to try and keep him hydrated. A visit to the vets the following day just confirmed that he had a high temperature and was getting dehydrated and they suggested a blood test which we declined, so they suggested giving him some antibiotics which we agreed to.

Checked all the reviews online for this product and was horrified to read the same thing happening to lots of other cats, the reviews which came from worldwide spoke of cats becoming severely ill following the product being added by spot on treatment. One of the things I noticed was someone suggesting to wash the product off the cat using a mild detergent such as washing up liquid in the bath water, and we did this straightaway. Within hours the cat perked up and came off the sofa for some food.You can tell the vet until your blue in the face that this product is real bad but they wont listen, in my opinion the product is dangerous and should be investigated as just too many cats becoming ill using this. And why are vets still offering it without giving these warnings.....Certainly wont be using this again!!!!!

Don't Waste Your Money! – 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… Read more

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.

Gets rid of fleas but has unwanted side effects – I have used this product on a couple of occasions as the old Frontline stopped working years ago. I hate using spot on flea treatments, I'll be honest. The idea that my cats have poison throughout their skin for a month is horrible. So I use Advantage twice a year just to kill any eggs, larvae etc. The rest of the time I use natural methods… Read more

like D.E. I have noticed that this product does not protect for a month as advertised. In fact, the last time I used it, it lasted less than 2 weeks. Anyway, my boy cat suffers every time I use Advantage. I have had to take him to the vet EVERY TIME I have used Advantage. The vet originally denied that the Advantage played a part. However after keeping a diary, he was forced to admit that it must be the spot on. Our boy cat gets bladder inflammation every time I use Advantage on him. So much so, that our vet has warned us not to use it anymore on our boy cat. He suggested Comfortis - yeah right - with the horrific reviews including seizures and death, I'll just have to be more vigilant with vacuuming, washing and combing my cats from now on. No more chemical products.

Use with Caution – I purchased the Advantage II for my two indoor cats after using Frontline for many years because I thought it might be a better choice. A day after applying it on both my cats my female vomited a few times during the night and by the next day her eyes were swollen and red and her ears were bright crimson red. I immediately took her to the vet. He… Read more

gave her a cortisone shot and cortisone medication to take for a week. He felt she might have ingested it somehow. The next morning she was notably better. I can not recommend this product after this experience nor will I be purchasing it again.

Beware!!! Cat killer!!! – 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… Read more

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.

Works alright but fleas work up an immunity after awhile – 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… Read more

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!

Dangerous product - my cat became very sick - needed to be hospitalised – My cat became very sick, sapped of life, no appetite, depressed, unable to walk for 3 weeks. Reaction to Moxidetrin.

Left burn mark, bald patch and then infection – 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.

Big cost and not entirely effective – Tried this product to rid us of flea infestation to no avail. Still found large adult fleas after 2-3 days of using drops. These fless showed no signs of slowing or dying and it was only 2-3 days after applying. Obviously doesn't stop reinfestation from pet's environment (and yes we threw out everything before application). Flea collar by seresto was only product to work.
