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 Fleas Evicted, Cat Offended Within a day or two, I stopped seeing fleas doing their little parkour routines across his fur. Scratching went down noticeably... It’s also actually waterproof... Still effective afterward, so points for that. Verified buyer Bought for my kitten Within 6 hrs I was seeing fleas in various states of death. Less than 24 hrs later, my kitten is free of scratching, licking, and chewing on the pests.

All Price Quality Application Ease of use Rosi Mar 9, 2024 Happy kitty happy Mum! The media could not be loaded. 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!

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 Show more Show less 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! Show more Show less 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. Show more Show less 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. Show more Show less Mary New May 26, 2026 Trusted vet quality flea care, works fast Love this for my cats. It uses a trusted vet quality formula and comes with a 6 month supply, which is amazing. It protects against ticks and breaks the flea life cycle. It starts working within 24 hours and is super easy to apply. It kills fleas, eggs, and larvae. Easy to use, effective, and reasonably priced. Highly recommend to anyone dealing with fleas and ticks. Show more Show less AZ Apr 2, 2026 Fleas Evicted, Cat Offended I used this on my cat, who weighs about 10 lbs and believes personal space is a human invention. Application was surprisingly easy—part the fur, squeeze, done. He gave me a look like I had betrayed him deeply, but that’s standard for anything that isn’t treats.The good news: it works. Within a day or two, I stopped seeing fleas doing their little parkour routines across his fur. Scratching went down noticeably, and I didn’t have to burn the house down, so that’s a win.It’s also actually waterproof, which I didn’t think I’d need until my cat decided to step in his water bowl like a tiny chaotic gremlin. Still effective afterward, so points for that.Now for the downsides: the smell is… not great. Not horrible, but definitely noticeable for a bit after application. Also, the application spot can look a little greasy for a day or two, so your cat may temporarily look like they lost a fight with a hair gel bottle.No bad reactions in my case, but as always, probably worth keeping an eye on your cat the first time you use it.Overall, solid, budget-friendly option that does the job—just be prepared for mild judgment and a brief period of “why is your neck like that?” aesthetics. Show more Show less rmac Feb 16, 2026 Tick protection works Love how this protects my cat from ticks and fleas. The formula feels trusted and it really works. Very easy to apply too, which is a win with a kitten. My cat is around dogs a lot, and I want steady protection, and this delivers. I apply it every month and I've never seen a flea or tick on him. I will definitely keep using it. Show more Show less Cecilia Gonzales Jan 11, 2026 Great flea and tick prevention for cats This product is really easy to apply, which is a big plus. I appreciate that it breaks the flea life cycle effectively and comes with a 6-month supply, saving me from frequent purchases. The waterproof feature is a bonus since it stays effective even if my cat gets wet. Overall, it fits my needs well and seems to do the job without any issues. Show more Show less AW83 Dec 7, 2025 Best flea treatment! I've been using this on my cat for a couple of years and haven't had any fleas! I live in an apartment building, so fleas are pretty common to find, but shockingly, none have gotten to him. I love that there's zero side effects and that it doesn't affect his mood or anything. The only issue I've had is him lightly/occasionally scratching where the medicine was applied on the first day. His skin doesn't look irritated or anything so he's probably trying to clean off the medicine.
