Prices and coupons for 1 package (4 doses) of Advantage II for Cats under 5 lbs.


I’ve been using Advantage for Dogs on cats for many years by purchasing the Dogs derivative and splitting it into smaller doses appropriate for my cat’s weight. This seemed to be a common practice with vets as the Active Ingredients of the Dogs and Cats derivatives were identical.
When Advantage II came out, I continued with the practice of using the Dog product on Cats only adjusting the dosage.
However, after a while, Bayer added a “Do not use on Cats” warning on the packaging of Advantage II for Dogs.
I can understand why Bayer would put such a warning from a marketing point of view. However, as the non-active ingredients are not listed on the packaging of either product, I’m not sure whether there might be another reason.

I was wondering if you had any insight on this question of using Advantage II for Dogs on Cats.

I look forward to hearing from you,

Advantage II for Cats Review - Best flea treatment for cats

I treated my 10 pound cat and my 12 pound dog with Advantage II, using the dosage recommended in this article. Even though the new package says do not use on cats, the ingredients and % are the same, and I had no problems. I applied to cat at base of skull so she could not lick it, and made sure she did not get close to the dog for a few days. All are well, healthy, and basically flealess! Occassionaly I find a flea, but the flea appears to be dying. The cat probably pcked-up the flea, brought it in, and I found it before it died. This works great! and is a real cost savings~!! Thanks so much for all your help! *Smile*
