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.

Questions & Answers

24 Customer Questions

It's been 3 weeks and my cat still has a bunch of fleas on his ears and nose. Should I apply another treatment and hope it will eventually work or assume it's not going to work for him and try something else?
Answer by ChewyAug 02, 2018
If you see fleas on your cat within a month after your pet receives flea treatment with Cheristin for cats, it is most likely these are new fleas that have very recently emerged from pupae and jumped onto the cat. These new fleas will be killed quickly before they can produce eggs that contaminate the environment.Consistent monthly application of Cheristin for cats should be maintained to provide continued protection for your cat against these fleas.

This is a new product to me. In addition to killing adult fleas does its properties include a flea growth inhibitor ?
Answer by ChewySep 25, 2017
This product is intended to kill fleas but not flea eggs, pupae and larvae. Female fleas can lay up to 50 eggs per day so there is potential for a large buildup of eggs, larvae and pupae, resulting in a constant supply of new adults emerging in the cat’s environment. We always encourage pet parents to treat all pets and surrounding areas in and outside of the home.

Is there shelf life on this product. If I don't use all of this product will I be able to use it next year
Answer by ChewySep 10, 2018
This product does not have an expiration date as long as the tubes remain sealed.

How do I know if the Cheristin flea medication is made in USA and bought from a reputable source?
Answer by ChewyDec 06, 2019
Cheristin for Cats is manufactured in Clinton, Indiana. Chewy sources all our products from manufacturer approved distributors or directly from the manufacturers. Chewy takes pride in ensuring that our furry friends’ well being is always our top priority. We have worked hard to partner with all of the manufactures to deliver 100% authentic products.

Using in place of Revolution, not so impressed

Recently its been hard to find the traditional Revolution (not the plus) so I decided to order this product instead. I have used it in the past with good results for my eldest cat who can be sensitive to products and experience head tremors from some products. This time I treated all my cats and I wasn't very impressed by the volume of liquid I had to apply, the smell and the mess it created on their fur (even hours later). Most unfortunate were the large red sores one of my cats ended up with in the treatment area just hours after I applied it. Cheristin used to be a good product but now I am questioning using it. The packaging has changed so im curious if the product itself has also changed?

Works, smells terrible

This product does kill fleas. Sometimes I have to use another product when Cheristin stops working, usually AdvantageII. And when that no longer works, I'll go back to Cheristin. The smell is strong and sweet, but I guess it's meant to be a reminder that the cat has been treated with a flea product and to not touch that area for a few days. I really don't like the smell.

We love this product

We have been using Cheristin for a few years. My last shipment had the vials out of the foil and it was so much easier for me. Our cats’ fleas seemed to have become immune to most of the other products. Cheristin kills the fleas and we can sometimes go more than 4 weeks. Since we don’t have carpet and have leather furniture, there are not many places for the fleas to burrow and lay eggs. I do notice an odor (as do the cats) but it is not offensive to the humans in the house.

Doesn’t Work!

After my cat got tapeworms, my vet recommended switching flea meds and trying this. He used to be on Advantage II and I never saw fleas on him, however she said the worms were likely from fleas and they are becoming immune to Advantage II. Within 3 weeks of using this flea medication, I was noticing a few fleas on my cat. A few weeks later I noticed around his chin and neck would get bumpy scabs. I later learned this was a reaction to flea bites. After trying this for a few more months (I bought a 6 month pack) I decided it wasn’t working well and looked for something new. I now use Revolution Plus. I never see any fleas and all of the scabbing has gone away!

Packaging is awful, product evaporates

The new packaging does not protect the tubes. When I opened the box, the tubes fell all over the place. The previous packaging had each tube protected by a foil seal, which was great. The new packaging is not at all protective so the liquid inside the tubes evaporates over time.

Med's for my Cats

This was our first use of Cheristin for Cats. The previous medication used for flea treatment caused one cat to have such a severe reaction that for months he literally chewed and scratched himself up, to the point of bleeding. It's taken him 3 months to recover. The Cheristin did not cause him to react as he had before. Now all the cats seem less irritated by the Cheristin medication.

LOVE the new applicator!

So I’ve been using this for 2 years and I really love it! For those saying they struggled to get it open, towards the beginning of last year the applicator now just twists open, the cap doesn’t come off anymore, it’s a twist and squeeze type of thing which I appreciate as it makes it less messy when tossing as it stays in one piece and I’m not picking up a cap that I had to get meds on to open. If you keep up with the doses it’s an amazing product thank you!

Great Stuff

I had a horrible infestation of fleas. I started using the Cheristin and in @ 3 months the fleas were completely gone from my cats and my home.

Kills ADULT fleas on cats

It killed the adult fleas. My cats had no negative side effects. Those who complain about opening the tube: just twist the top- no need to remove it totally.

packing could be better

always happy with how prompt my supplies get here, but every time I order small items like flee treatment or delectables its packed in the same box as the heavy cat litter and gets smashed, the cheristin packs were all over the place and i had to search foe all the doses which are small ane a few slipped into the cardboard packaging
