  • Good product with a lower price.
Style: Cats over 1.5 lbs Size: 1 Count
Liked the price. I used frontline on my cat Ms. Jones first. It did get rid of initial fleas. However, within a week they were back.I did bathe her and yes I did treat my home as well. I was able to treat her again, but waited 3 & 1/2 weeks. The frontline did not do well or last again. So the vet recommended pet armor. This one has worked great. I will say that cats like people are all different and some thing work good on one, but not the other. But, this item is awesome and I highly recommend it. ... show more

  • Budget-Friendly Flea Control That Actually Pulls Its Weight Budget-Friendly Flea Control That Actually Pulls Its Weight
Style: Cats over 1.5 lbs Size: 1 Count
I went into this expecting “discount flea medicine energy” and came out pleasantly surprised. PetArmor Plus is basically that underrated store-brand cereal that tastes suspiciously like the expensive one… but doesn’t make your wallet cry. 🐾 The Good Stuff (Why it stands out) First, let’s address the big elephant (or rather, itchy cat) in the room: this uses the same active ingredients—fipronil and (S)-methoprene—as pricier brands like Frontline Plus. That means you’re not getting a watered-down knockoff—you’re getting comparable chemistry at a lower price. What makes it genuinely better than many similar products: * Breaks the flea life cycle (not just adult fleas) It kills eggs and larvae too, which is crucial unless you enjoy playing “flea whack-a-mole” every week. * Fast-acting and long-lasting Starts working within about 24 hours and protects for up to 30 days per dose. * Waterproof formula Because cats + water bowls + chaos = inevitable. It keeps working even after exposure to moisture. * No vet visit required This is huge. You’re essentially getting “vet-quality” protection without the vet bill. 😼 The “My Cat Has Opinions” Section (Cons) Let’s be honest—no flea treatment is perfect, and this one has a few quirks: * Slight chemical smell at first Not unbearable, but your cat may temporarily smell like they’ve been working in a lab. * Application drama If your cat acts like you’re committing betrayal every time you apply something to their neck… yeah, that still happens. * Effectiveness can vary slightly Works great for prevention and mild infestations, but if your home is already hosting a full-blown flea rave, you may need backup (sprays, cleaning, etc.). 🆚 How It Compares to Similar Products Compared to other flea treatments in the same category: * Vs. premium brands (like Frontline Plus) → Nearly identical active ingredients, but significantly cheaper. → Main difference is branding, not chemistry. * Vs. cheaper generics → More reliable and better formulated than ultra-budget options that sometimes only target adult fleas. * Vs. collars or shampoos → Way more consistent, longer-lasting, and less hassle than weekly baths or hoping a collar does its job. 🐱 Final Verdict If you want something that’s: * Effective without being overpriced * Scientifically legit (not herbal wishful thinking) * Simple monthly maintenance …this is a very solid pick. ... show more

  • Will Kill Your Cat!!!!!
Style: Cats over 1.5 lbs Size: 1 Count
Almost killed my cat within 5 minutes!! Applied as directed, 5 mins later my cat is drooling uncontrollably, lethargic and just falls over, out cold!!! I had to run him under cold water, to shock him alive, and do CPR on my cat until we could get him to the emergency vet! This stuff is dangerous!!! Please use caution!!! Had we left after applying he would be dead! ... show more

  • Effective flea and tick treatment for large dogs
Style: 89-132 lbs Size: 1 Count
Does what it says. The PetArmor Plus for X-Large dogs effectively kills flea larvae, flea eggs, and ticks, which gives me peace of mind. The waterproof feature is a plus, especially for active dogs. However, it could be more affordable and easier to apply. Still, it's a reliable option for keeping my dog protected from pests. ... show more

This product has worked well for my dog. It was easy to apply, and I noticed a difference within a short time. My dog has been more comfortable and scratching less.

  • Dog version was useless, cat worked well
Style: 23-44 lbs Size: 1 Count
So we thought we would try to save some money because I timed poorly on our animals seresto collars, and it's almost time for snow here in upstate NY (no fleas out when it's -5!) So I bought this for both my red heeler mix and the cat one for our inside cat. Well didn't work at all. My dog is now infested with fleas, but the cat is not! Don't try to skimp just buy the Seresto collars. ... show more

  • My dogs thank you
Style: 5-22 lbs Size: 1 Count
This is a real review and I am not a robot. I have bought this item several times for my dogs and we have no fleas anymore. We used to have a really bad flea problem and now it’s all gone not one single fleet. I’ve not seen in months because of this product and another product that I’ve also reviewed on here. It’s a natural Solution that you put on your dog food for fleas and ticks. It works. Oh my gosh, I cannot tell you how much I’m so thankful through this product and the flea collar. ... show more
