CAPSTAR Blue FAST ACTING for Dogs & Cats 2-25 lbs.
A single fast acting dose of Capstar (nitenpyram) should kill the adult fleas on your pet. If your pet gets re-infested with fleas, you can safely give another dose as often as once per day. To administer CAPSTAR tablets, place the pill directly in your pet's mouth, or hide it in food. If you choose to hide the tablet in food, watch closely to make sure your pet swallows the pill. If you are not sure that your pet swallowed the pill, it is safe to administer a second pill.
We recommend you follow up CAPSTAR treatment with a monthly flea control product such as PROGRAM, Frontline or Advantage. Then keep CAPSTAR on hand for the times when there is a visible flea re-infestation.
Cats (4 weeks of age and older and 2 pounds of body weight or greater)
Dogs (4 weeks of age and older and 2 pounds of body weight or greater)

I use these on the feral cats in my neighbor. It works great and I like that it can be administered more often then once a month.

For elderly or sick animals, this is the only product that kills all of the fleas safely, for 24 hours. This used with a safe monthly flea control product eliminates fleas
Works for Us! by 6 Maine Coons Plus 1 from North Carolina11/25/2013
2013 has been a bad year for fleas. Capstar in addition to topicals has kept up with the challenge. With 6 Maine coons I need the value in purchasing from Entirely Pets.... I am not a vet... I do follow the guidance of mine...
Fantastic Price! by cowgirlup19 from Byhalia, MS10/29/2011
This is absolutely the best price I've found on this product. I have 8 adopted adult cats (my babies) that I use this product on in conjunction with frontline plus. This has saved my babies from the horrible sores and scabs that come with the flea allergies. I'm always thrilled when I can purchase more reasonably priced products.
Great Stuff by Manypets from Atlanta, GA04/02/2012
This product is one I have been using for years and it has always done an excellent job in reducing the onslaught of fleas that come with warm weather. I most definitely recommend it for all pet owners and rescuers.
