The flea's stay off of my cats and they are not always chewing and scratching themself. The price is very reasonable and a fraction of the other name brands. Sandra Tick and Flea Prevention Worth Every Penny It's easy to use, and feels like vet quality. I trust the formula to do its job well. The fact that it breaks the flea cycle, protects against ticks and kills flea eggs and larvae is really impressive. It's also a very effective flea treatment for my cat. Shear K. A simple solution for pesky fleas I really like the features of the PETARMOR flea treatment—it's easy to use and does the job effectively. Applying the doses was a breeze, and my cat didn't mind one bit. Since starting this treatment, fleas have become a thing of the past.

It kills adult fleas, flea eggs, flea larvae, ticks, and chewing lice, and helps interrupt the flea life cycle. Its listed tick targets include deer ticks, brown dog ticks, American dog ticks, and lone star ticks. Deer ticks can transmit Lyme disease. Check your package label for the full list of uses. ### How long does PetArmor® Plus take to start working? PetArmor® Plus starts killing fleas within 24 hours. Follow the package label for what to expect with ticks; the approved product information does not give a separate tick-kill timeline. ### Can I apply PetArmor® Plus right after bathing my cat? Check the package directions about bathing before application and make sure you follow them. The treatment is waterproof after application, but that does not establish how long to wait after a bath. ### How often should I apply PetArmor® Plus for Cats? Each application provides up to 30 days of protection. Follow the package directions for your cat's next application rather than applying extra treatment early. ### Can I use a diluted dog flea and tick product on my cat? No. Choose a product specifically labeled for cats, rather than diluting or partially applying a dog treatment. Check the label for the animal, age, and weight before application. ### When can children play with my cat after application? Keep children away from the application area and follow the package's contact instructions. Check the label for when it is safe to resume play; a specific wait time is not confirmed by the approved product information. ### Does PetArmor® Plus for Cats expire, and how should I store it? Refer to your package for shelf-life and storage directions. Store it out of reach of children and pets. The approved product information for this page does not verify a specific shelf life, temperature limit, or refrigeration instruction. ![A person holds up a box of PetArmor Plus for Cats while an orange tabby cat sits on a patterned rug and looks up at them.](https://media.brandclub.com/pages-studio/_app/app_petarmor_dtc/assets/1793367663379-VJLKn2uN.jpg) ### 4.2 Star Rating ## Discover why customers choose us We've collected over 77,701 reviews from shoppers on our website and major retailers. All Price Quality Application Ease of use Rosi Mar 9, 2024 Happy kitty happy Mum! After my son noticed tiny slithering bugs on our 9 month old tabby, I bathed him and tried other treatments that didn’t work. My son had noticed tiny slithering bugs on our cat Chivo, so we quickly treated him with Pet Armour Plus on February 4th. Since then, we haven't seen any more bugs, and Chivo can enjoy the outdoors without worry. Thanks, Pet Armour, for keeping our kitty healthy and bug-free! Show more Theresa Wauligman Jun 21, 2025 Flea & Tick Drops That Actually Work! 🐾 🐱 5-Star Review: Effective Flea & Tick Drops That Actually Work! 🐾I’ve tried several flea and tick treatments for my cat, and these drops are by far the most effective. Within 24 hours of application, I noticed a huge difference—no more scratching, and I actually found dead fleas in her bedding. After a few days, she was completely flea-free and so much more comfortable.The application was simple—just part the fur between the shoulder blades and squeeze the drops on the skin. My cat tolerated it well, and there was no irritation or greasy residue. One dose has lasted the full month as promised.What I really appreciate is that it works without a strong chemical smell and doesn’t make my cat groggy or sick like some other brands have in the past. If you’re dealing with fleas or ticks, this treatment is fast, reliable, and safe for your furry friend. Highly recommend Zoe Lampkin Feb 8, 2025 Good price! My cats do fine. I’ve been using PetArmor Plus for Cats for a while now, and it works great! It effectively keeps fleas and ticks off my cat, and I love that it’s waterproof and long-lasting. The application is easy, and I’ve noticed a big difference in my cat’s comfort. Definitely a cost-effective alternative to other leading brands. Highly recommend! Lisa Putman Sep 3, 2023 5.0 out of 5 stars These really do help with fleas I have these on a monthly autoship so I won't forget to buy them as I have 7 cats to treat.I hadn't treated them in months and after the first application I did notice less scratching.I just applied the 2nd application yesterday. Haven't noticed any of them scratching today.The tubes are purple with a long neck. There's just a small amount of serum in the bottom and the long neck prevents spillage.I also find this brand a lot less expensive than others. Just the facts Nov 29, 2025 started working in days First time trying this petarmor on my 7 pound cat. Got the one for over 1.5lb cats for him. He lives in a forest and been getting ticks once a week. A few days after the initial application he has been tick-free ever since. Been almost a month now. This stuff works perfectly for us. I highly endorse this product. Kenda Oct 23, 2026 Ready? Set? No regret! Worth the $ After my Princesses and Prince devil spawn decided I was worthy of their love (about 90 minutes) and forgave me for putting something on their neck, I noticed 2 alive adult fleas on my arm from where they had layed on me for about 10 minutes.I had no expectation of this product because I had been paying double the price for 1 cat for 3 months than I got for 3 cats for 3 months. In this scenario, the negative saying "you pay for what you get" does not fit. Will only use this brand in the future. Jessica Oct 22, 2026 Best flea drops around This is the only flea drops I trust! A lot of flea drops I've tried were indeed cheaper but they didnt seem to work. I have 3 cats so even if one flea lives they can jump to another cat and lay eggs. This may be pricey but it works so well and I never worry about one flea getting away. 10/10 flea drops, kills every single one Justme823 Oct 15, 2026 Worked Beautifully! My cat was itching like crazy even though she is strictly an indoor cat. We live in the country though, and this is a bad time of year for fleas. Unfortunately, they can jump on us while we are outside and we can bring them in. While I don’t think my cat had a severe flea problem, I can say that one dose of this and she completely stopped itching within a couple days. I was afraid to purchase it at first because of some negative reviews saying it didn’t work. But you have to keep in mind that flea bites will continue to be irritated and make a cat itchy even after all the fleas are dead. The itching will stop when the flea bites heal. Thankfully, I caught it early on and it worked quickly. My cat had no side effects at all, and she is able to rest comfortably now with no more itching. I will definitely continue to use this and would recommend it! The price is amazing, too, compared to the big brand names and prices in pet stores! Danny Oct 2, 2026 It does what it is supposed to do Here on my farm this past summer, the wild rabbit population seem to be overwhelming and rabbits is cute as they are always bring a hoard of fleas. Taking my little Pomeranian outside to do her business she started picking up fleas and transferring them to the house and then transferring them to my cats. And then a flea problem started I treated my cats with this product and a product also from the same company was used to treat my dog. I treated the property with the black flag flea and tick spray and I treat the house with wonder side flea spray that is a spray and play product. That’s safe for animals but can’t use it directly on the animal and it knocked down the flea problem within a month time once you beat the flea cycle everything is perfect and the vet has said he detected no fleas on my animals whatsoever the product does what it says. It’s supposed to do if use properly. Melanie Mader Sep 11, 2026 Easy application, no smell Bought this as one of my cats was having some skin irritation (never saw fleas or flea dander) It is easy application behind the shoulder blades and stopped whatever was causing his itching. It doesn't cause any burning or skin irritation on it's own (at treatment site). I can't detect any smell when I apply it. Works well for it's intended purpose.I found this for 50% off during Prime Days - even better! See more reviews ### Ways to buy PetArmor View
