Effective and easy to apply flea treatment
Been using this for weeks and it really makes a difference. The application process is straightforward, which I appreciate since my cat isn't a fan of treatments. Its waterproof feature means I don't have to worry about bathing my cat immediately after. I feel confident it prevents infestations and protects against pests like fleas, ticks, and lice. The price is affordable, making it easy to keep up with the monthly schedule. Overall, a reliable choice for keeping my cat safe and comfortable.

Good value for the price!
We purchased PetArmor for Our furbaby, who was not responding well anymore to the Frontline (which works excellent but he's sensitive now). He got an infestation within a week after missing the Frontline while We struggled to find him another good product. We live South so the fleas and ticks are TERRIBLY invasive during this time of year. We came across this product and decided to try it and see if he behaves better with it. He's reacting better, not licking and scratching himself so much at all like with Frontline, it works pretty well for the cost, and some things make it work better: Washing your kitty first and removing as many living fleas and as much gooky flea matter as you can. Then wait until kitty is fully dry and apply the Pet Armor. It DEFINITELY works way better if you bathe kitty first, even if during drying kitty picks up a few more fleas. The first time We used it We did not bathe them first and while it killed about 80% of the pests, they still lingered and eventually came back. The next time We used it, We bathed Our babies first and then applied it... They have NOT had anymore fleas or ticks, and We're POSITIVE they're still outside haha. Using in conjunction with vacuuming and household treatment. We notice when We keep the carpets and Our babies sleeping areas EXTRA EXTRA clean, wayyyyy fewer fleas linger and the meds last longer. We admit the Frontline kills flea and tick infestations etc VERY quickly, even in carpets and bedding with just a simple application to Our furbabies, but for the price and strength, it's no real loss to vacuum etc to help the Pet Armor along. Keep kitty contained for 1-3 days after application. Not just with Pet Armor, but Frontline too... Within 24 hours after application, some dying ticks and fleas still have strength for a few days and tend to run and jump off of Our furbabies, increasing danger of biting Us too, so keeping kitty contained helps to keep the house from crawling with dying critters while kitty is lounging on everything. Also fleas and ticks don't die as quickly (they die, just not as quickly) with PetArmor as with Frontline or Advantage, so monitoring their activity is easier when kitty has to stay in place. Pet Armor does leave a white residue, wipe it away after a few days. The days before We applied PetArmor, We had about 50 fleas We handpicked from various places within Our home. It was harsh!!! Within a week after, We've seen exactly two fleas, and that was after Our babies went outside for about an hour. We removed them and haven't seen any since. We also found a dying tick on one of them, no longer attached to the skin. No more scratching at all. We're still thinking of using Advantage, which Our babies Love, but it doesn't kill ticks so We're considering using it when the fleas are just TERRIBLE but We don't see ticks, and the PetArmor once the fleas are well eliminated and to prevent ticks (like maintenance). The reasons are because We still are concerned about if PetArmor will cause any long term reactions to Our sensitive baby due to the strength of the tick killing formula, and Advantage, like Frontline, kills fleas REALLY quickly, and all around the home, which is easier when We don't have the energy to vacuum 3x per day. Overall We definitely recommend Pet Armor if your kitty is sensitive or unable to take Frontline or if cost savings is important. It lasts much longer with good hygiene and household habits, and is DEFINITELY DEFINITELY better than nothing and worth the cost!

Worth it
Best treatment I've ever used. A little more pricey, but worth it. My cats hardly react and they are kept safe even in the woods

AFFORDABLE AND EFFECTIVE!
This product works very well on my 3 cats, 2 of which are indoor/outdoor. It’s very affordable, dries in well and has never caused any adverse reactions in the few years that I’ve been using it. I apply it every month-even in the winter months- because the last thing I want is a flea infestation in my house! It’s an effective product, keeps my cats comfortable and gives me peace of mind without breaking the bank. What more can you ask for?

I am very disappointed and regretful
I was a loyal customer to this brand for years! It has always worked so well! But this fall we’ve had a lot of issues with fleas! And ticks too! But the fleas infested the cat and dogs, even tho I gave them this topical and had each month, on time. Just so happened a week after putting it on the cat, i noticed he was infested with fleas! I had to buy good flea shampoos for dogs and cats, had to spray and vacuum and revacuum and re vacuum again. Had to get the cushions. CLeaned up and my van and wash all the bedding and still be able to play etc. I called the vet who told me to use capstar for a couple days then bathe them for at least 5 minutes. Two days after the baths I was told to use a 2nd topical treatment and that I should use k9 advamtix … since I’m broke and still had this product, I chose to use it again instead of ordering the other. Sure enough the cat was re-infested again!! Had to give him yet another flea preventive they’ve been ok since I think but I’ve been cleaning like crazy, vacuuming over and over again just to be sure. And using flea spray. 1 cat and three dogs bathed twice in a week and two doses of topicals plus capstar to help kill the fleas fast. Vet said the yard should or could be treated as well but on 3 acres that’s not going to happen. Idk if they switched the formula or what but it is not the same and not working anymore. For the dogs or cat. Only the capstar or flea shampoo really helped. Very upset. Oh! And the vet said even though pet Armour is using the same main ingredient, they can’t match the efficiency in how the formaula spreads through the dogs fur/skin, to allow it to work properly. Even applying it in a line between the shoulders and down farther, still didn’t help.

Great value and easy to use for my cat
So happy I bought PetArmor for my cat. The product is affordable and comes with 6 applications, which is a good deal. I find it really easy to apply and it effectively protects my cat from fleas, ticks, and lice for 30 days. Overall, a convenient and reliable choice for flea and tick prevention.
