Best treatment ive
I read a lot of the reviews before buying this and saw mostly positive reviews on it. We've had trouble with flea infestations for years. We had two cats but one past away but we currently got another girl for my sister. Maze [Older] (5 year old Siberian) by girl has long fur because she's a Russian cat so she has long fur, and Nala my sister's cat [Baby] (10 month old tabby mix), they currently got fleas because we got Nala fixed at Harbor Humane Society in Michigan and unfortunately she came home with fleas. We thought we had gotten rid of them with liquid neck treatment and flea collars for them but they came back. We never really were able to find a good or fast way to get rid of them. It's always been a struggle for my family. In all honesty I was suspicious about how this would work for our girls. But I was pleasantly surprised by the results. I believe because Nala is younger and has much shorter fur she had far more fleas than Mazikeen (a.k.a. Maze). Due to the reviews on this product I tried certain things knowing out girls and made sure to look for certain things. I crushed a pill for each of them and mixed it with certain wet food that is more liquid than meat. It helped it blend better and our girls prefer the liquid over the meat most of the time so it worked out perfectly. Maze ate hers and acted perfectly normal except for a slight more itching than normal. Nala on the other hand began itching after bout thirty minutes to an hour. She began crying and wanting to run around. She became super itchy but after about three or so hours she calmed down and finally fell asleep peacefully. The fleas were literally falling off of her dead. I could not be more satisfied with a product I've ever bought for effective flea treatment. There was absolutely no smell or anything bad coming from it. For the price I paid for 6 pills was definitely worth the money I spent on this product. The value works so well. I would 100% recommend this product for cat flea treatment. The fact that one pill for each killed so many fleas is insanity. And paying such a decent price for them is amazing for a below poverty level family with two cats. Though it does not kill the eggs it is extremely effective for killing the adults on them. I will definitely be spreading the word about this product because it helped me so much. I will definitely be buying this product again if I need a fast effective treatment for our girls.

Great price for the quality, works within an hour!
The quality of this product can’t be beat for immediately killing live fleas. It’s not for flea prevention, but you can use it with your regular prevention medicine without making your cat sick. Dead fleas happen within an hour, and because it’s a pill, there is no weird smell and the cats can’t lick it off of each other. No hair loss that I have noticed, either. I haven’t noticed any side effects at all, actually.

Definitely by again when needed
The price went up Nooo!! People started to clock in and realized this stuff works!! Not for long term,but it gets the job done. No hair loss,there's no smell, just the right size to add it to a little bit of treat and they don't even realize they took it.

Helpful and affordable
Pills are never easy to give cats, but these are small, so that was helpful. I do believe that this accomplished the intended task. I coupled this oral treatment with a flea bath and later a topical treatment. Getting 6 pills for this price was a good deal, in my opinion. I would recommend this product to others and I would purchase again, if necessary.

yeah
it works exactly how directions say. it is NOT a one time use thing like my grandma thought when she got it. it only kills adult fleas for about 6 hours so if any jump onto the cat after that time or any eggs or larvae hatch, youll have to repeat the treatment which isnt really a bad thing.

Fast acting,kills bugs starting in 30 min
My cat is 24 yrs and can not use advantage anymore this works fast.She has no reaction to it.I shampoo her also to remove any eggs.

Works, but cat refuses to eat willingly/unwillingly.
My cat hates them, and she can smell or taste them in almost anything. She doesnt react poorly to them, they work well, but if your cat refuses or can't be forced to eat them, then they aren't going to help. I'm also not really a big fan of forcing my cat to eat anything she doesn't want to eat THIS badly.

The ONLY Flea Treatment I Trust — Works FAST and Works EVERY Time!
PetArmor CAPACTION is one of those products you try once… and then you never bother buying anything else again. It is truly the ONLY flea treatment I use now, and for good reason — it works fast, it works consistently, and it works exactly the way it promises. If you’re a pet parent like me, you know the panic that hits when you spot a flea. I want something that starts working immediately — not days later, not “eventually,” but now. And that’s exactly why I stick with CAPACTION. Within 30 minutes, I can see it doing its job. My pets stop itching, the fleas start dropping off, and peace is restored in my household. This stuff is powerful without being complicated. No messy topical liquids, no weird lingering smell, no stressing my pets out trying to rub something on their neck. It’s a quick pill, easy to give, and they’re done. Honestly, it’s a lifesaver for pets who hate topical treatments or for busy days when I don’t have time for a whole routine. And let’s talk results — because PetArmor CAPACTION delivers. Every single time I’ve used it, fleas are gone same day. Completely. I’m talking a night-and-day difference. It kicks in so quickly you can literally see relief happen in real time. For me, that kind of dependable performance makes this product worth its weight in gold. I also appreciate that it’s affordable, especially compared to the big-name brands that cost a fortune but don’t always work any better. This gives premium-level results on a budget-friendly price tag, and that’s a win for any pet household. I’ve tried other flea treatments in the past, but NOTHING works as quickly or as reliably as this one. At this point, I don’t even experiment anymore. PetArmor CAPACTION is the only thing I buy, the only thing I trust, and the only product that has never let me — or my pets — down. If you want real, fast, effective flea relief, this is it. One dose and you’ll understand why I refuse to buy anything else. 🐾✨
