I smash the tablet up with a little wet food or tuna, and it works within 48 hours. You must vacuum and wash every surface the cat touched before giving the medicine, or you may waste your money and time. Verified buyer 100% Recommend Within an hour after administering one pill all fleas fell completely off. No side effects, skin irritation or weird behavior. The product is pricey but worth it for prevention from an infestation into carpet, furniture and soft goods. Lucia C. Easy to administer and works in hours Love how fast this works, my cat relaxed in under 6 hours. So easy to give, no struggle at all. It covers kittens 4 weeks and older and scales up to 25 lbs, which is perfect. The 6-dose pack is a great value and finally flea relief I can trust. Cathey M.

All Effectiveness Value for money Fast acting Price Lyubov Oct 26, 2025 Amazing Product – It Really Works! The media could not be loaded. Amazing Product – It Really Works!Wow, I never knew they even had this kind of medicine pill for flea!My cat is a Scottish Fold ( high-maintenance breed), so I was really nervous to try any medicine. I didn’t know if it would work for him or if it might make him sick. But I decided to give it a try and honestly, I’m amazed!I gave him one pill just like the instructions said, and in about 30 minutes the flea started jumping out. I was shocked! I even took pictures because I couldn’t believe how many came off. I had no idea he had that many!My cat is an indoor cat and only went outside a couple of times, and that’s probably how he got them. This pill worked so fast and so well. I’ll check again tomorrow to see if he needs another dose, but so far it’s perfect.If your cat has flea— don’t even think twice. Just buy it! You’ll love it. It’s super effective, easy to use, and my cat is totally fine after taking it. Highly recommend! 🐾 Show more Show less July Berry Aug 26, 2023 5.0 out of 5 stars Easy, works great! The media could not be loaded. I have a stray/feral cat that has mange. I started him on a mange relief treatment first to help with the scratching, crushed it and put in wet food. About 4 days later I have him one of these and it worked perfectly. I give him one once a month the past 3 months, and so far between the 2 treatments the condition is improving very well, it will definitely take time dealing with mange. The sores were pretty severe so it will take several months to fully heal. But in 2 months you can definitely see the difference, like a new cat. Show more Show less Tabatha Perez Apr 25, 2026 Work's! I gave this product 5 stars because it truly works! PetArmor CapAction started killing fleas very quickly after I gave it to my pet. Within a few hours, I could already see a big difference. It’s easy to use, and I love that it doesn’t leave any mess like topical treatments. My pet felt much more comfortable and stopped scratching so much. Definitely a great option if you need fast and effective flea control. I would absolutely buy it again! Show more Show less Kitty Royse City Mar 28, 2026 These work for scratching without the mess. No smell, oiliness or risk of skin irritation like some vial-type applications! We have been buying these tablets for years and they help! Our indoor/outdoor cats stop scratching after an hour or two. The only side effects are increased scratching after 30 minutes of administering and lasting an hour or two. The value is worth the comfort and health risks of what fleas can cause. One cat is difficult to give pills to while the other is fairly easy. It just depends on your pet. Lasts for a month. Show more Show less Sarah Dunham Oct 2, 2025 Gets rid of the fleas fast! I've been fighting fleas on the cats all summer. We don't have carpet and all their bedding is washed regularly. Bravecto and flea baths weren't cutting it. I got this on a whim and gave it to the cat with the worst problems and the next day there was notable improvement. If I did catch a flea on her it was either already dead or slow and easy to crush. Best thing is, if you get a new hatch out, you can dose them again!I gave it to the rest of the cats last night so hopefully this will be the end to the flea problem. Show more Show less Lindsay Gonzales Sep 13, 2025 BEST FLEA Med for Big Fluffy Cats The media could not be loaded. Highly recommend this product for fleas on your cat. Worked within 30 minutes and the next day my Norwegian Forest cat was flea free after fighting it for months. I put a pill in his food and he laid down and they all fell off, so make sure you let them sleep on a table or in the bathroom and all I needed was to wipe the dead fleas up. There were no active fleas left on my cat. I’m so thankful my cat can heal now. Show more Show less Tabitha Jun 23, 2025 This stuff works!! This stuff works! Our baby is an outdoor kitty and he got fleas really bad the past 2 months. One dose of this made an amazing difference. It killed literally almost all of the fleas on him. I only found 1 moving when I did a comb check! Our little guy didn’t have any kind of adverse reaction ( I was hesitant and monitored him for a few hours after dosing). He was really affectionate and happy to have his fleas gone 🙂👍🏼 I’ve attached a pic of our happy kitty for reference 😂🖤 Show more Show less khalil al-stouhi May 16, 2025 Make sure to always keep this on hand I have never written a review on any product that I’ve bought, but I knew I had to write a review about this. I live in the woods and have recently started letting my cats go outside. I had started itching on my stomach and under my arms, at first, I thought it was mosquito bites since it is the season. Then I looked at my stomach and it turned out to be flea bites. Then my mom came up to me and showed me her back and asked if this was eczema, I told her no it was flea bites. I usually use a topical medication every month for my cats, but it just wasn’t cutting it. I ended up getting a spray and I sprayed them and I also got them a flea collar. I didn’t know for sure if the fleas had died until I gave them this medication. My mom came up to me and told me to look on the couch, fleas had fallen off. I was very surprised with how fast the results were. I will always make sure to have this medication on hand, and I plan on buying more. Show more Show less Lindsey Dec 13, 2024 Works well to get rid of adult flees This product worked very well to get rid of adult flees. However, even after washing and using a flee comb, the flees came back. As stated on the box, it doesn’t work on eggs. My advice is to use a combination of topical formula in addition to the pills. They are small enough to administer. I stuck it in a piece of turkey and my cat ate it without incident. The flees were falling off within an hour. It didn’t have any adverse effects on my cat. Unfortunately, even after vacuuming and washing bedding, the flees did come back. Show more Show less peteygrizz Nov 9, 2024 Fast and effective My cat Rascal started acting strange, she was staring at the carpets and then started to avoid walking on rugs and was sleeping in closets all day, along with excessive scratching and chewing her fur. I finally realized she had fleas, which after 14 years of indoor/outdoor access has never once had, even when other pets did. One of my previous cats had a severe and fatal reaction to the common topical treatment so I was looking for a better option.This nitenpyram worked exactly as described. First it was easy to dispense as she readily ate her food with the pill concealed within. She didn’t even notice. It started working within 20 minutes as she was going nuts as the fleas panicked and after a few hours she calmed down. The photo is her sleeping soundly for the first time in several days. The relief it brought her was immense as she was suffering badly from the bites.I especially appreciate the safety factor since I lost a cat to another flea medication and was very nervous about using anything again. So glad to have my kitty happy again.
