    • Immediate relief for the cats!
Size: 6 Count
This worked wonders for all six of my cats! They are indoor, but I was leash training one and I think she picked up fleas. It was first time experiencing fleas. They were scratching so aggressively. They couldn't sleep. So, I bought this along with spray and shampoo to cover all bases and washed blankets and everything I could stick in the washer. Sprayed their cat beds and what not. It took about an hour for me to notice dead fleas on the floor. I gave them another dose the day after to make sure I got them all and they are officially flea free! ... show more

    • Easy cat flea prevention.
Size: 6 Count
It does the trick, my cats do better with this medication, tubes of topicals don't work for them, and it is far easier to crush the tabs and mix it with their favorite food or with toppers. They will eat every drop, and the capstar tabs without any nonsense or struggle. It works. A good addition to your flea prevention program Effectiveness: Florida is rife with fleas, and this product works. It is cost-effective also. ... show more

    • Worked great, no issues
Size: 6 Count
Got tired of fighting with my cat to do his monthly topical treatment. He hates it so incredibly much and it never even seemed to last as long as it should anyway. Decided to give this a try. Have done it once so far. Worked well, no adverse reactions with my little guy. I figure once to twice a week depending on his exposure and we'll all be much happier. I just hid it inside a soft treat and he never knew it was there. ... show more

    • Very Good Flea Oral Treatment
Size: 6 Count
I've been giving this oral flea medication for the last couple of months to my 4 cats, as I hate putting liquid poison on their backs. It helps kill fleas and larvae. I do have to smash it a bit and put in their wet food, as they are very picky eaters, but they do take it without problems! Also, I love that I can order it without a prescription! ... show more

Review Image by Heaven Heaven
We recently tried the CAPSTAR (nitenpyram) Oral Flea Treatment for our pets, and it has been a game-changer in dealing with flea infestations. As a pet owner with multiple animals, flea treatments are essential, and this product provides fast, effective relief for our furry friends. Fast-Acting and Highly Effective What stands out about CAPSTAR is how quickly it works. After just a single dose, we saw immediate results. Within 30 minutes, fleas were dropping off our pets, and within a couple of hours, the infestation was significantly reduced. It’s perfect for those times when your pets need instant relief, especially if you’re dealing with an active flea problem. Safe and Easy to Administer This treatment is incredibly easy to give to our pets. The pills are small and can be given either directly or mixed with food. Both of our pets had no problem taking it, and it didn’t cause them any distress. The oral formula is safe and gentle, so we didn’t have to worry about harsh side effects. Works Quickly Between Other Treatments While this treatment doesn’t provide long-term flea prevention, it is an excellent quick-fix for an immediate infestation. It works well when paired with a monthly flea preventive to ensure your pets stay flea-free in the long run. It’s perfect for situations when you need fast relief before starting a longer-term flea prevention routine. Great Value for the Price For the results it delivers, the CAPSTAR Flea Treatment is a great value. It’s affordable and effective, especially for pet owners who are dealing with sudden flea issues. One dose is enough to take care of the problem, making it a practical option for those who need quick action. Final Verdict: A Must-Have for Fast Flea Relief If you’re looking for immediate, fast-acting flea relief for your pets, CAPSTAR Oral Flea Treatment is the product to choose. It’s effective, easy to administer, and works quickly to eliminate fleas, providing much-needed comfort for your pets. ✔ Pros: Fast-acting, easy to administer, effective, safe for pets ✘ Cons: Doesn’t provide long-term prevention (but works well with other treatments) Would I buy it again? Yes, especially for quick flea relief! ... show more

    • Good flea medicine for cats

This stuff works really good on our cats, and is a good price for what you get. I've only ever used Walmart branded stuff and that stuff was not good. This stuff works well and really quick and I haven't boughted any other brand ever since.

    • THEY WORK
Size: 12 Count
I would have given a 5-STAR if not for being ripped off. These work great, BUT, I ordered a 2-pak and only received "1" box...was charged $64 for 6 pills instead of 12!!! I wrote to the seller, NO RESPONSE & thete's nowhere to ask for help. EXTREMELY DISAPPOINTED IN MY PURCHASE!! The product is really useful though & they do kill fleas right away. If you use these along with treating your lawn with triazicide you'll rid yourself of fleas for a year. We give a pill every other day for at least a week or so. I have 7 cats and not one of them has ever had an adverse reaction to the CapStar pill. ... show more

    • Effective and Quick Flea Treatment
Size: 6 Count
I've been pretty happy with this flea treatment. The six doses in one pack are quite convenient. The fast-acting nature of the treatment is a huge plus. It's great that I can give it as often as once a day, and it's safe for cats and kittens from 2 to 25 lbs, which offers much-needed flexibility. However, I wish the effect lasted longer and the taste was improved for easier administration. All in all, a good product. ... show more
