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.

Does this product expire?

Answer by Chewy • Jul 26, 2018
This product does not expire. All PetArmor products should be stored at room temperature in their original packaging and are good to use as long as the pipettes remain sealed.

Do the fleas have to bite to die?

Answer by Chewy • Dec 31, 2023
This treatment is applied to your pet topically and kills fleas through contact with the treatment on your pet’s skin so fleas don't have to bite to die.

This treatment is safe for all cats 8 weeks and older.

My cat had a very bad reaction to this product. It was so bad my cat's fur started to fall out at the point where I applied the medication. A sore started to develop too. I took my poor cat to the vet. They tild me if I didn't bring him in when I did, his condition would have worsen. This vet bill cost me $230!!! So buyer beware!

Product was easy to apply

The only problem was it did not make my cats stop itching. They can't walk 3 feet without stopping and scratching. Don't know what to do for them, not fleas!

I’ve been treating my cat with this monthly for over a year. I have never seen any fleas on her, but she’s allergic to all kinds of bug bites and still itches and licks herself raw. It could be anxiety. I don’t know.

Flea free

My cats are inside cats. However since I work outside a lot and could carry fleas inside I want to be sure my cats are protected.
