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.

Is this safe to use in multiple cat households on cats that love to groom each other? What if they end up ingesting it?
Answer by ChewySep 01, 2017
Once dry the formula is completely safe for normal grooming, and most cats will avoid the bitter liquid.

Can this be used on kittens?

Good Product

I've never used flea medication for my cat until recently. I took on cat for her vaccinations, the vet told me she had slight indications of having fleas & prescribed flea medication. I have 2 other cats that I started using this product on. One of those went for vaccinations a few months later. He was flea free. Have not noticed any negative side effects.

not bad

used this for the first time on my three guys and it took 2 days before i started seeing dead little buggers. like that it doesn't have a horrible smell like most other brands.

I like this brand as it works very well for me and all my cats. I live in the country and ticks abound every spring so it is really necessary. Nothing sadder than to see one of the feral cats sporting any number of them and not able to help. This product keeps ticks from biting and protects my own babies when they go outside. However, the ticks do ride on their fur and I have to check myself regularly but that I can do. man, I hate ticks!!!

Flea season

Mowing season equals flea season. My cats are all indoors but that doesn't stops the fleas. Unfortunately, Sentry Fiproguard did nothing to kill them. Just combed the smaller long-haired bobtail; still infested after flea treatment and spraying the carpet. Inexpensive but not worth that if it doesn't work.☹️

I was skeptical based off the reviews i have 6 cats and it’s keeping the fleas off them just not killing the ones left in the house from the eggs, i frequently find dead fleas on them all day. definitely re buying thanks!

Only kind for CHEWING and sucking lice....

PoultryDVM site lists Fipro as a parasiticide for chickens, I got the packet for kittens (should have bought the adult box...) I got this because it was the THREE WAY - you MUST get the type that kills chewing, biting AND sucking insects...

Fantastic value

The value is excellent. Controls fleas very well on my inside cats. Chewy is easy to use. Shipping is very fast.
