II Large Cat Vet-Recommended Flea Treatment & Prevention | Cats Over 9 lbs. | 4-Month Supply

II Large Cat Vet-Recommended Flea Treatment & Prevention | Cats Over 9 lbs. | 4-Month Supply

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.

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: 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.

Q: 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.
