"After years of dealing with flea outbreaks, I’ve found this pill to be a reliable, over-the-counter solution that kills adult fleas within 24 hours. It’s easy to give to my feral and domestic cats alike, and I appreciate that it’s affordable and gentle enough for kittens over 8 weeks old. I always see results quickly and keep it on hand as my go-to fix."

"PetArmor CAPACTION is the only flea treatment I trust now—it’s fast, consistent, and starts working within 30 minutes. No messy topicals or stressful routines—just a quick pill and my pets are itch-free the same day. The price is great compared to big brands, and the results are always dependable. If you need real, immediate flea relief, this is it."

"I've tried several flea and tick remedies before, but none have worked as well as these supplements. My cat is noticeably less itchy, her coat is shinier, and she loves taking them with her food. Plus, the price is unbeatable compared to other brands. If I could give more than five stars, I would!"

"With multiple cats in my household, I was searching for an easy, effective solution. These chews made a clear difference—no more scratching, and my cats take them without fuss. There's been no stomach upset or side effects, and the large bottle lasts a long time. Highly recommend for peace of mind!"

"I have both indoor and outdoor cats, and since starting these chews, flea and tick problems have disappeared. My cats eat them easily, and it's been a stress-free switch from topical treatments. Happy, healthy cats—what more could I ask for?"

"After trying many options, I found that these vitamins made a remarkable difference in my 12-year-old poodle mix. She's now playful, healthy, and energetic again! She doesn't love the taste, so I crumble them over her food, but I'm thrilled with the change in her wellbeing."

"We switched to these after chemical treatments like Frontline and a vet prescription stopped working. Since starting the treats, we’ve had no more fleas or ticks in the house and I love that it’s a natural, chemical-free option for my cat."

"I’ve only been using this for a couple of days, but my pet seems to be scratching and gnawing less. If this continues, we’ll both be much happier with the results."

"I was amazed by how Capstar eliminated fleas so quickly, but I do wish their 30-day option worked as well. It's impressive for immediate results."

"The best part is that fleas are gone within half an hour. It’s perfect for a single-use treatment, especially for my indoor cats. Just remember, it won’t keep new fleas away."

"In my experience, it only lasts a day. It didn’t solve the problem long-term, so keep that in mind if you need ongoing protection."

"With several cats at home, I needed a hassle-free and reliable flea solution. These chews are a daily treat my cats look forward to, and I've seen noticeable improvements in their skin and coat softness. Most importantly, we've had zero flea or tick issues, and I love the added benefit of natural immune support."

"I've struggled with fleas on my cats in Texas, and after trying this supplement, I noticed it quickly eliminated all adult fleas. My cats, even though they're usually picky, ate the tuna-flavored tablets without any fuss. The combination of Nitenpyram and Lufenuron seems to be working well for us, and the bottle lasts a good while with several cats. Overall, it's been a great value."

"My wife's cat had a persistent flea problem, but after giving her the first dose of these tablets, we stopped seeing any live fleas within two days. The cat had no issue with the tablets, especially when broken into smaller pieces. We're still waiting to see how it holds up over a month, but so far, the results are promising."

"I tried these tablets for my cat, but she still has fleas pretty bad. Even with a flea collar, I didn’t see much improvement. My cat loves tuna, but I had to crush up the tablet and mix it with her food to get her to eat it. I think there might be better options out there for us."

"My cats just go wild for these treats—I've tried everything, but with these, they're practically jumping out of their skin to get them. I've noticed their fur looks better, and the flea problem that kept coming back is finally under control. Definitely a must-have in my house."

"I have a cat who's incredibly picky with food, but he can't resist these. I feel good about giving them since they're made with real ingredients and actually help keep fleas away."

"I was skeptical at first, but after using these for a while, the flea count went down, and my pets love the taste. I'll definitely use them again."

"I've noticed my cats love these treats, and I haven't had to use any of those expensive flea medications lately. No fleas so far, and I appreciate that this doesn't stress them out or cause skin issues—it's just easy and they eat them up right away."

"A few of my cats are a bit finicky, but the ones who eat these have shown big improvements—no more sneezing or nasal discharge, and their flea problems are almost gone. I just wish there was a catnip flavor for my pickier cats."

"My dogs enjoy these, and I can confidently say they keep fleas and ticks away. After a bad reaction to prescription meds, I switched to these and have had no issues since—plus, the dogs are happy to gobble them up."
