Why is the item called "Bayer K9 Advantix II Flea and Tick Control Treatment for Cats"? The Bayer K9 is, of course, for dogs.

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.

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?

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!

Is this 6 month supply a 6 pack of tubes?

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.

Does this kill ticks? If not, what do people recommend for ticks?

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.
