Check the product label for information on application and potential side effects. Advantage II Large Cat flea protection is effective on both indoor and outdoor cats.

Review: TL;DR: Works quickly, easy to use, and stopped a full flea flare up in a day without turning it into a huge chore. We grabbed this during a sudden little outbreak, and I was honestly relieved at how simple it was to use. The tube opens cleanly without splattering, and the liquid goes right onto the skin without any fighting or trying to part the fur forever. Our big cat barely reacted, which made the whole thing easier. What stood out most, though, was how fast it worked. By the next day, the scratching had almost completely stopped, and the fleas we saw earlier were gone. There’s something comforting about using a product that doesn’t need tricks or follow up treatments right away. It just gets in there, does the job, and lets the whole house calm down again. I also appreciate that it’s unscented. No strong chemical smell lingering on the cat or in the room. As the days went on, the difference stayed steady. No more tiny specks showing up, no more frantic grooming, and the cat settled right back into normal behavior. It didn’t irritate his skin or leave any oily patch that lingered forever, which sometimes happens with other treatments. This one soaked in cleanly and didn’t bother him at all. Having something that clears things up fast is a huge help when you’re juggling pets, kids, and everything else. It feels like a reliable tool you keep on hand just in case, and it’s reassuring knowing you’re using something vet recommended with ingredients that have been around for years. There’s a good sense of trust that comes with that. What I like most is the peace of mind afterward. Once it kicked in, the whole flea situation was just done, and that kind of quick resolution is worth a lot. It’s the kind of product you’re grateful to have on hand before a problem turns into a bigger headache. Tip: Apply it when your cat is relaxed and already settled so the dose goes on smoothly without any twisting or fussing. Don't let them flick their head and splash it in your eyes! Hope this helps! =)
Review: I like to know things. One question I had was how in the *#*@ does an indoor cat get fleas? I looked it up and it's a lot more common that one might think. Fleas are jumpy little things that find their way onto shoes, clothing, and other things people bring home with them. Unless one never leaves their house, there's a very good chance of bringing fleas in with you without ever knowing. Long story short, once I noticed the fleas, I took steps to get it under control. A flea comb is essential! My vet recommended a topical, so I spent the big money and went with a FRONT of the LINE solution. It was supposed to be the best in the biz. I followed the directions and it did absolutely **nothing** for my cat. I was still combing live fleas out of her by the hundreds. It was a total waste of money. A week later I applied another dose of the FRONT of the LINE topical. Again, it did absolutely **nothing** for her. After which, I tried a flea spray to no advantage. She hated it, it smelled terrible, and because she hated it, I couldn't get it far enough into her long fur for it to do any good. We ended up using the spray on our furniture and her carpets. We did NOT want to put her in the bathtub. I mean, if you've ever bathed a cat in less than a full suit of armor, you know what I'm talking about. I purchased a dry flea & tick shampoo along with the same brand of spray. The waterless flea bath "does" kill fleas after a few seconds in the foam, but she hated it so much her behavior changed drastically. Drastically enough that it scared the crap out of me. She stopped coming in the living room, stopped perching on the back of my chair, wouldn't jump on me for cuddles, was lethargic, and stopped sleeping on my chest after I went to bed. She wasn't acting like herself. At. All. That said, I was still combing live fleas out by the dozens. That number would have been a lot higher but since she was already not acting like herself, I didn't want to stress her out even more by doing more combing. Enter Advantage II Large Cat. I always do a lot of research before using a new product. I had seen the nightmare reviews of skin burns and worse. Even so, there were a lot more good reviews than bad...and I was getting desperate. Using the Advantge II Large Cat was my 2nd to last resort. IF it didn't work, she was going to get a water bath...and I don't have a suit of armor. I was looking as forward to doing that as I would look forward to dragging my body over razor wire...which is essentially the same thing. I am very happy, thrilled in fact, to report that this product worked beautifully! I properly applied the product on 10/29/25 at 3pm. I was very careful to make sure I parted her long fur enough for it to get on her skin. The product takes a full 12 hours to reach is max potency. After 12 hours, I was coming less live fleas from her. It is now 10/31/25 and at last combing, there were NO live fleas. Zero. Ziltch. Nada. Her behavior is returning to normal, she's not scratching/biting like a little banshee anymore, and she had no adverse reactions to the product. I will continue to be diligent with the flea comb to see if she needs another treatment next week. Knowing what I know now, I wish I wouldn't have wasted my money on the FRONT of the LINE solution and used Advantage II Large Cat from the get go. I could have saved my cat and myself a lot of undo stress and worry. I highly recommend this product. Note: If one is worried about their cat's skin, I recommend using one or two drops to "test" how your cat will react to it before giving the full dose.

## Questions & Answers

**Q: Why is the item called "Bayer K9 Advantix II Flea and Tick Control Treatment for Cats"? The Bayer K9 is, of course, for dogs.**
A: Please be sure to use ONLY Feline Advantage on cats and use ONLY the dog Advantage on dogs! The use of canine Advantage on cats WILL kill them giving them severe neurological damage! I wish that Advantage would make the packaging TOTALLY different for cats and dogs, it would help. Especially with people who may not see the difference at first glance. My elderly mom accidentally applied the large dog Advantage to her cat and it had to be put down. Mom has felt horrible about it. Awful experience. Also about dosing, I have a 19 year old cat and I have used feline Advantage on him every summer for about 3 months for well over 17 years. It works wonderfully for him. I have always used the large cat product but since he has lost some weight this year I called Bayer and asked if I should use a smaller dose. The person at Bayer explained that Advantage works on body AREA as well as weight. So even though my cat has lost some weight (he's 9 pounds) his body AREA is still the same (loose skin)  and so I have been applying the large cat dose and it has worked well for him this summer with no ill effects.  I cannot speak to the authenticity of this Amazon product as I purchase my Advantage from the local pet store.

**Q: When using this medicine, do I also need to flea bomb or spray the apartment ? Or will the medicine kill all fleas in the apartment, as well?**
A: You'll find a wide range of advice on here.  I can only tell you what has worked for me on several occasions.  This topical treatment will kill only the fleas that get on your cat.  There are several options for your home.  They range from safe/natural formulas to strong pesticides.  The all safe/natural offerings work for a short time and only kill the fleas that come in contact with the spray.  I keep a bottle outside to spray on my feet and ankles to kill the fleas from outside that have hopped on me while in the yard.  Great for this and for bedding.  Next, as for bombs - there is only one that I have found that works.  Most bombs are cans of spray that has a button that locks down to empty the can of spray.  They may work but only cover a very small area effectively.  Raid makes a bomb that you drop into a supplied plastic cup with about an inch of water in it.  When the bomb canister hits the water, it will begin to smoke.  The smokenfills the entire area.  Three cannisters come in the box and can cover a small house effectively, every nook and cranny.  It is called Raid Fumigator.  I have NEVER had to use it twice.  This type of treatment requires you to remove ALL pets for about 6 hours, but it does work.  Raid also makes a carpet spray that works well.  But again, pets must not be around it until the fumes die down - about 30-40 minutes.  Two other options are Boric Acid or diotemaceus earth (food grade!).  These two products are applied similarly.  You sprinkle them on carpet or furniture and take broom or brush to rub them in.  This will take a few days to a week or so to get control of a home invasion.  They work by cutting the exo-skeleton of fleas, roaches, etc and cause them to dehydrate.  The Boric Acid can cause irritation to some pets or people, where the diotemac ous earth is 100% safe other than breathing the fine dust that occurs only when you are applying it.  Both work great!  The problem with a lot of people complaining that a product doesn't work is that they don't realize that the flea you see is only 5% of what is in your house.  The other 95% are eggs (laid about 50 at a time) and the larvae.  There is a cycle that last up to several weeks.  When these doubters kill the 5% adult fleas and then find more fleas a few days later, they think it doesn't work.  But in reality, they are see new hatchlings.  That's where the Boric Acid and Diotemaceus earth come in handy if you can't use the Fumigator.  An infested home can seem unsurmountable but try the products that you feel safe with, give it time and vacuum everyday you can and you will win!

**Q: Is this 6 month supply a 6 pack of tubes?**
A: Hi Doreen... Actually, I bought the 4 pack because I have four cats.  I had earlier in the month bought a 4 pack someplace else, so I had two treatments for each cat.  I did the treatments three weeks apart (the instructions say it is OK to do if you wait seven days).  I bought the 9+ lb. package as three of the cats are well over that weight.  One cat is a bit smaller and I didn't use quite all of the tube on her.  None of the cats had any bad reactions, and it worked well for three of them.  The other cat (partial Maine Coon) had some results, but not so good.

**Q: Does this kill ticks? If not, what do people recommend for ticks?**
A: To get rid of fleas and ticks use Frontline Plus. I started to use it on mine a year ago it killed the ticks and fleas. I reapply it every other month and I haven’t seen one since.
