Is this for fleas and ticks?
A shopper on Sep 15, 2017
BEST ANSWER: Advantage II is for fleas only, no tick prevention.
It says 6 month supply but I thought this is a once a month treatment. How many applications of treatment is included in this price/ offer?
A shopper on Mar 10, 2017
BEST ANSWER: This comes with a 6 month supply, 1 supply per month for the next 6 months.
My kitten is 5 to 8 pounds would this be ok for him?
A shopper on Mar 31, 2016
BEST ANSWER: No, cat must be over 9 lbs.
when I type in tick Advantage II pops up but it does not state that it covers tick control. I need flea and tick, cats are outside cats. Frontline doesn't have very good reviews do you offer anything else?
Robin O on Dec 27, 2015
BEST ANSWER: We use Advantage II on both our indoor and outdoor cats and we have never had a problem with ticks. We have tried different, less expensive brands and they have upset our cats skin. I recommend Advantage II for both indoor and outdoor cats. Hope this helps!
Is there a generic Advantage II for cats?

my cat is nine pound is it okay if i use over 9 lbs?
A shopper on Oct 7, 2014
BEST ANSWER: It is not uncommon to hit this "gray" area when ordering based on weight, In my experience it is best to go with the nine pounds to be certain that your cat (or mine) gets complete coverage.
