This is nice in that it kills fleas and also protects against heartworms, ear mites, some intestinal worms and skin mites. Can be used at 9 weeks of age in cats. I know some clients are turned off by the cost, but it depends on what your cat might get exposed to. I think every cat should be at least protected against fleas, heartworms, and intestinal worms. You can use multiple products, or you can find one, like this, that does it all.

Pros: gets a lot of parasites

Cons: cost

We are slowly switching the shelter to this product as out inventories of other products diminish. Not only is it a single flea and heartworm preventative but also wiorks actively against 3 stages of hookworms 2 stages of roundworm and whipworms. An important component for those who like to bring their animals to such places as dog parks.

Pros: Combines treatments

Cons: Costs

I really like Advantage Multi for cats. It is easy to use, you just put it in a line on the back of their neck. It not only kills fleas and ticks but kills heart worms, ear mites, and some intestinal parasites. We use it at the shelter and I haven't seen any adverse reactions in the cats there.

Pros: Does fleas, ticks, heartworms, earmites, and worms!

Cons: none

This product is very easy to use and has very efective on our cats. There has been no irritation to their skin, no struggles as we apply the product...and I like the little included stickers ...I place them on the calendar as reminders.

Pros: easy to use and effective

Cons: none

I have an indoor cat that some how got flees. I applied the Advantage for about 3 months and the flees are gone from the cat and the home. I did not need to bomb the house as the Advantage too care of them.

Pros: Works Great

Cons: Lasts only 3 weeks
