Review: Our three cats have had fleas for a while. Attempts to rid them of fleas have not been effective. Twice daily fine toothed combings have collecting disturbing amounts of fleas. Topical treatments between the shoulder blades were also not as effective as we had hoped. With no adverse reactions appearing in any of the reviews, as well as, the advertisers claim that this treatment was safe for kittens- I purchased these tablets. Prior to administering the tablets we read the instructions on the outside of the box. (See image) About fifteen minutes after administering one tablet to each of our three cats- as if the fleas were attacking each cat at once- each cat began scratching and biting and licking at different parts of their bodies. This went on for quite a while. Then, one of our cats, our “Ragdoll, had an adverse reaction. He began to run around the apartment, to vocalize, to salivate, to have an increased heart rate, to tremble, to pant, to have difficulty breathing, & to salivate. It was disturbing to witness. I dialed the tn on the packaging, and surprisingly/thankfully we spoke to a representative by the name of Oz, she was calm, helpful, reassuring- wonderful- us? Not so much. After a few hours, as Oz, had advised, their symptoms diminished, and overnight all three appear to be back to normal. FYI, this morning, unbeknownst to us, yesterday, we discovered that there was an additional information sheet, literally, stuck to the inside of the box. And, lo and behold, there is an adverse reaction warning. (It does appear that the product worked effectively; however, according to the adverse reaction warning- have that cat carrier ready in case an emergency vet visit becomes necessary. Thanks, again Oz ! Addendum: The next day, Thurs. Mar. 28, 2024, right as I was finishing up this review, I received a call from Lindsay, another representative from Capstar, she was following up to verify whether or not our cats were ok- they were, and are. Thanks, again Lindsay !
Review: I feed up to six feral cats who live in my neighborhood. I started letting a couple of them come inside last winter. My legs got all bit up though during the warm weather, so I started grinding up Capstar Flea Treatment in their food. I also vacuum right after one or both of them leave, and have a fleas spray, plus I use hand sanitizer on my hands and socks (which one in particular loves to rub up against my ankles), so it's not just the medication alone, but I'm happy to say that I haven't gotten any bites lately. I have a subscription to get it delivered regularly, and the last time I got bit up I ordered it more often. In addition to six cats, there are possums, crows and raccoons that raid the cat food, so I'm not always sure how much of the medication is getting into any one cat. It's also possible that some or all of the bites came from mosquitoes. So while I'm pretty sure it's working, I'm not using it under controlled circumstances. Give it a try and see for yourself, and then let us know here. 😺

## Questions & Answers

**Q: How long is 1 dose intended to last?**
A: 1 dose lasts 24 hours.  It kills all living fleas but not the eggs.  If you decide to do a topical later on like Advantage, wait at least 2 days before putting that on your cat.  Advantage or Frontline kills the eggs in addition to the living fleas

**Q: What are the ingredients?**
A: Thank you for your inquiry.  The active ingredient is Nitenpyram.  Unfortunately, the other ingredients are proprietary.  Kindest Regards, PETIQ

**Q: can i crush this into powder?**
A: Thank you for your inquiry.  We would not recommend crushing the product into a powder.  Please feel free to contact us at 1-800-781-4738 with any other product questions.  Kindest Regards, PETIQ

**Q: Is this not a maintenance product to keep fleas and ticks off of cats? Or it’s just a one time jumpstart.**
A: Thank you for your inquiry. Per label, a single dose of CAPSTAR 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. This product is not labeled for use as a prevention or against ticks.
