How often do you have to administer. This is a feral cat.
Answer by ChewyFeb 03, 2021
This treatment starts working quickly and efficiently, killing 90% of adult fleas within 6 hours. A single dose should kill the adult fleas on your cat. In the event of re-infestation, you can safely give your cat another dose as often as once per day.

1/25/21 I want to know is this pill water proof.2 Does the fleas have to bit first. Is this a month long or 1 day medication the website is not very good
Answer by ChewyJan 26, 2021
CapAction is an orally administered tablet that does not wash off. Once your pet has swallowed the tablet, the active ingredient, nitenpyram, goes to work within 30 minutes. Once the nitenpyram enters the bloodstream, the fleas ingest it when they bite your pet. If your pet gets re-infested with fleas, you can safely give another dose as often as once per day. CapAction is safe for dogs, puppies, cats, and kittens 2 pounds of body weight or greater and 4 weeks of age or older.

how long does the product last on the cat to treat fleas?
Answer by ChewyMar 08, 2022
A single dose of CapAction 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. It will begin working within 30 minutes.

can this be used as a preventative or is it just for cats that already have fleas?
Answer by ChewyMar 27, 2022
CapAction Flea Tablets for Cats is suitable for treating infestations and is not a replacement for a preventative. The product starts working within 30 minutes and continues to work for 24 hours. If your pet gets re-infested with fleas, you can safely give another dose as often as once per day.

Better price, same ingredients as competitor

I purchased a different name brand of this same product from my local petstore, and it cost me about $45. Later, I saw this PetArmor brand offering the same product here on Chewy and through other both online and local sellers for roughly $15 less than what I had paid for the other name brand. It's the same ingredient, same dose, and same number of doses for a lower price. I've found this product to work within the same day because I've found fleas coming to the surface of my cat's hair and they just list there lifelessly near the outer fur after they've been affected by the medication. I have found this affect to only last a about 3 to 4 days. It's not a whole solution, but using it as part of a multi-pronged approach, it's a great tool. It offers immediate, temporary relief from the irritating itching also. For pets who have been suffering from fleas for a while, it's a quick reprieve from all the scratching and they can sleep and rest peacefully for a few days while you start addressing the infestation in the home and yard. I got this product for a feral cat who I've tamed and was spayed/vaxed through a TNR clinic, but is local veterinarians will not see her because of her history of having been feral. So I am limited to non-Rx options to maintain her medical care. It was easy to give her this pill - I used a pinch of a chicken flavored pill pocket to coat the pill, and she ate it eagerly. Good luck!

What situation is this for?

This product works. Technically. Once. For a couple hours. After the first pill given to your cat, quite quickly the fleas start acting weird. They hop off the animal and run in circles. "This is great!" you tell yourself, until they're back literally the next day. It just confuses and kills the adult fleas on your cat for a couple hours. Their eggs hatch, and you're back to square one. It solves nothing. You're better off getting a big name brand for twice the money that takes a week to work, because it'll actually solve the issue instead of tricking you into thinking you've found a magic fix for a couple hours.

Used along with Advantage II Flea Spot Treatment

I don't know how my cat got fleas because he's an indoor only cat. I noticed a flea on him one day and I figured that where there's one, there's more. I ordered both PetArmor CapAction Flea Tablets for Cats and Advantage II Flea Spot Treatment for Cats, over 9 lbs. Between the 2 of them, I got rid of the fleas on my cat. I had to give my cat a second pill 2 days after the first one because I didn't think the first one got rid of them. He was still scratching and licking a lot. A few days after the second pill, most of the scratching and licking were gone. I'm glad I ordered both items.

hit or miss

I've used this for years only because its almost cheap enough since I have to treat 8 cats!. I used to find it in capsules, & open them up into food. These have to be smashed with a 'pestle" then mixed in food. As far as effectiveness, its hit or miss it seems. Sometimes it works, or maybe i need to give another dose right best with another flea med but I forget the one I use when I can get it. Luferon? If you only have a couplke of cats. I'd opt for something stronger.

Sort of Works

So the first pill works, every additional pill seems to have no effect at all. Oh and the fleas came right back. I don’t know how!? To date I’ve given my cat five pills on five separate days and I just saw a flea on her. She’s an indoor cat that never ever goes outside. What a waste of money! I wonder why Chewy sells a product that doesn’t work?

Worked for a day

It worked for maybe a day? No side effects but I have fosters. I can't afford to give them each one day. I cleaned all bedding and areas and did my due diligence, but it was ultimately a waste of money.

Waste of money

My kitties never stopped scratching after taking this, there was no obvious relief. The vet has used the Capstar brand before and the 24 hour effect was noticeable. I will not purchase this brand again and do no not recommend it.

Worked within 30 minutes

These pills were fast acting against fleas on both of my cats. Make sure your pet meets the weight requirement before use. My smaller cat handled it without any side effects. My larger boy, anout 18lbs, did act irritable, but it was due to a reaction of the fleas dying, not the pill (it explains this on the instructions). To my understanding you have to use a topical flea treatment along with this pill.

Fleas hatch out every two weeks so you need to treat the environment as well as all pets in the house. You will keep sees fleas if you don’t. This medicine only lasts for about 24 hours and inly kills adults. (I am a licensed veterinary technician)

Critter Mom

Be vigilant ... one of my cats had a adverse reaction to this pill. He was hyperactive, panting, salvation and pupil dilation ... thankfully it only lasted for about 20 minutes so I did not have to seek medical aide. The other 3 were fine so I will just make sure the one cat never takes it again. Did the job of getting rid of the fleas for the next day or so.
