Can definitely see results
Got this for my two kitties last week together with flea collars. Gave them the pills with their food, had an hour later I could tell it was working because they started itching and scratching ( a side effect of the medicine). I gave them a bath immediately to stop the itching, put their collars on and then for the next few days I vacuumed dead fleas from all over the house!! This thing really works, my house was infested, but after thorough cleaning, fogging and washing I can finally say that we got rid of them

Review for CAPSTAR Blue for Dogs or Cats 2-25 lbs (6 tablets)
Worked well with fleas that are full grown. Still have to bath on top of giving pill to kill all fleas on pet. Also have to treat home and yard to get rid of all fleas. So giving the pill is not the only meds you have to buy.

Love Capstar
This is a great product to kill fleas really quick. Great in conjunction with monthly flea products and to get all fleas off your pets while your cleaning/de-fleaing the home environment too.

Better than Frontline
Frontline did not work on our 2 cats, but this did. Cut each pill into 4 pieces and mixed it in each dish of canned moist food. All gone and easy.

Capstar flea killer
I use this to kill fleas a day or so before applying topical treatment. It also comes in handy when traveling with my cat to my son's vacation home so that no fleas are spread there.
I feel that it is safe to use and experienced no problems with it having used it off and on for several years.

5 Stars!
Any time I try a new product for my pets, I always check the reviews starting with the worst first. While I did see some adverse reviews of Capstar, the majority were rave reviews so I decided to give both my dog and cats a dose. Out of 4 animals, none had a bad reaction, none acted weird or distressed. The dog (80 lbs) was the only one who scratched somewhat, but not excessively; one of the cats scratched for about 30 minutes. The following day, during flea check, all 4 had no visible live fleas. Will repeat the process once a week for a total of 3 weeks, per vet, while following regular flea elimination tactics (vacuuming, monthly dose of flea med, etc). Great product!!!

Ineffective.
I was given to understand in the product description that results would be forthcoming within 30 minutes
after application. I have not seen any favorable results. The cats are scratching more than ever.

Works great!
I love Capstar! I works just as it claims and quickly kills off any fleas present on your pet. There is some slight itching as the fleas die off but it doesn't last long. If your pet needs quick relief from an infestation, use Capstar. If you want to get rid of all fleas prior to an application of topical flea meds, use Capstar first. It's a great product. None of my cats or my dog have had any bad effects from it.
It's not meant to be long-lasting, but rather quick relief and to maintain a flea free pet between topical flea meds.

Tablets for Flea Control
Finally, a pill for my dogs for flea control. I was sick and tired of the other liquid flea control, and my dogs hated it. The liquid had to be placed at the base of their neck and down to the tail. It smelled, was oily, and it just looked awful. Now we just have to give them a pill, and that's it. Also, I now have it for my cat.

Causes great distress
I used Capstar on my 16 lb 6 yr old cat and it was disastrous! She is ordinarily sedate but this pill made her go wild - running around like her feet were on fire, jumping up and down on the furniture, meowing loud howling type meows. Her heart was beating a mile a minute and her tongue was flickering in and out. I called Animal Poison Control and they said the effects could last up to 4 hours. It was horrible watching my cat in such distress and I am just thankful that it didn't cause her permanent damage. This is a very dangerous pill, it should not be on the market.

Good flea control
I am happy with the capstar blue for my cats. I use them in between monthly applications of revolution. Pill is very small and they don't mind too much, having to swallow it.

Great for stopping flea infestation
I've used this product for 3 cats now (2 of my own and now my mom's cat). All three of the cats had a bad flea infestation. This pill works wonders. It kills fleas on the animal so that you can get ahead of your flea problem and make some serious headway! I highly recommend Capstar to anyone who wants to combat their pet's fleas quickly and safely. Follow up with regular monthly flea meds and you are good to go!

Excellent : Removes Fleas Fast
This is the best to immediately get rid of any fleas! I've used this for many years on both my dogs & cats as it is safe to use on them both. I like keeping this on hand so it takes care of the problem especially for any inside/outside cats & dogs who may bring fleas into your home.

a short-term solution
I first got Capstar through my vet. Because Frontline was not protecting my cats from getting fleas, he suggested this product as a short-term solution for getting rid of the fleas they had on their body. (Only works for 24-48 hours). And it does kill them. I keep these handy so that whenever I see a flea they are given a pill and the fleas are gone. In the meantime I am trying out some other longer-term solutions for achieving a flea-free home.

This is for backup protection
Phoebe the cat and Hamish the dog are two years old this month, and were on Advantage last year, and I just re-ordered for 2014 season.
Because we live in front of a small park full of small mammals, I am concerned that both, especially Phoebe need back-up. Imagine last year she made friends with a skunk, I saw them cavorting through the dark. So, Advantage alone was not enough. I got bitten by flies when she returned home.
This week the sound I heard several nights at the patio door was made by a racoon, then there are many wild rabbits. This is life next door to nature and the many perils for domestic animals.
The season will be handled well with the monthly dose of Advantage plus the CAPSTAR
Blue that covers the weight range in both animals. I was bitten last year because Phoebe spent nights outdoors. This time I am prepared to handle before I get an infestation.
I like the service, fast shipping and good prices.

Worked great
Used in conjunction with Advantage, my cats were infested and the Advantage just didn't seem to be enough. Gave them the Capstar an dthen the next day the Advantage, we have been flea free for the past month now.

ABSOLUTELY AMAZING!!
Kills fleas almost instantly, providing much needed relief to your cat(s). Always continue with your chosen monthly flea control, too, but Capstar is great when you're dealing with the inevitable infestation that can occur in the height of flea season. Gave this to my cats once a week for 4 weeks and they and our home are now totally flea free. Safe and effective with no side effects whatsoever. Highly recommend Capstar for all your pets as well as the cost savings on Entirely Pets...a reputable American company.

I have a feral cat that has TONS of fleas. Can I crush the capstar and put it in his food?
2 Answers
I think so. I would withhold food from the cat until you know it’s really hungry and then try it. Pills of any sort can throw off the taste of their food so the hungrier the cat is the better. Worth a try! Capstar works really well, so fingers crossed!

This doesn't keep fleas off, just gets those on them at the time off. If infested, use this then use something else to keep them off.

I used it with a cat that I couldn’t catch to use a topical treatment with. I personally would worry about using it weekly although it is supposedly safe to do so. I only used it periodically. Considering the cost of cap star, I feel a topical treatment is preferred.

The capstar product does not tell you how long its' effects last. could you give or get that information for me?
1 Answer
Capstar is a flea treatment, not a preventive. Though it begins working within 30 minutes of initial administration and eliminates all fleas on your pet within 4 and a half hours- it does not provide long-lasting protection against future infestations. Capstar can, however, be used in conjunction with a flea preventive such as K9 Advantix II or Frontline Plus for Dogs available at the URLs listed below:
