Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

will this work on 9lb and over for cats
Answer by ChewyNov 09, 2017
This treatment is available in an easy-to-use, fast-acting topical application specifically formulated for cats and kittens over 1.5 lbs, so each monthly dose will give your cat the same protection.

What's the difference between this and the pet armor plus?
Answer by ChewyAug 13, 2017
PetArmor Plus contains (S)-methoprene while PetArmor does not.

I got my boyfriend a kitten that had a couple of fleas on it; then it progressed and got worse when exposed to other cats in their house, that go outside. Would this product cure all of the cat's fleas and rid them for good?
Answer by ChewyOct 13, 2017
This product is intended to kill and repel fleas, ticks and chewing lice.

Can this product be used at the same time while my cat is taking the pill program (Lufenuron)??
Answer by ChewyMar 22, 2019
We urge you to speak with your vet whenever starting a new or mixing two treatments together.

Easy & Effective

Our indoors cats got exposed to fleas through a careless contractor a few years ago... that flea infestation was the worst nightmare, we were dealing with the problem for MONTHS. I learned my lesson and began applying flea treatment on my cats each month, even though they are strictly indoors. I've been using PetArmor for over 2 years now, and with monthly applications both of my cats have remained flea free! Our cats love to sit by the open screen door or opened windows on a sunny day, and we don't have to worry about them getting fleas from outside because this treatment does its job. At first it was difficult for me to apply on them without really holding down the cats, but as they have gotten used to the process and as I've gotten quicker, it has become a really simple once a month application. You just squeeze the tube onto the back of their head and use the applicator to work it down onto their skin, which takes a few seconds. I give the cats treats after applying so that they forgive me faster :)

Purrfectly Priced!

Been using Pet Armor on my cat for years, but have never found it anywhere other than Chewy at such a great price! Works great on my 50/50 indoor/outdoor cat!

Worst EVER!!!!

I purchased this to treat my cats and followed the directions to the letter along with making sure that all of their bedding and anything that they slept on was free of fleas. Halfway through the 1st month of treatment, I had to retreat all 5 of my cats again. All this stuff seems to be doing for my cats is making the flies multiply. I would advise anyone thinking about buying this product to save your money. I have spent a small fortune with no results at all. I am really disappointed in this product. I really wish that I could get my money back for the purchases that I made.

This is worthless

I applied as directed....fleas are not affected. I applied again in 2 weeks, although directions say only once a month. Both my cats still have many fleas. This use to keep my cats flea free. The past year it does nothing. I am going to stop wasting money purchasing this product. Do not buy!!

Inexpensive way to treat my cat for fleas. He’s an indoor cat but I needed something for the summer months on the back porch

So Far No SMELL!

Easy to use, no chemical smell! My 5 cats didn't run for the hills after applying, which is very unusual. I'll buy again.

Didn't work

I was hopeful that this lower priced flea treatment would rid my kitten of fleas. I even bought the dog treatment at the same time. I'll be returning the dog item.

Hit or miss

There was a time where I could count of this to work for my cats, that time has ended. It doesn't matter where you buy it from. It just sucks now.
