Product Overview

Cheristin® for Cats is a topical flea treatment designed specifically for cats. Cheristin’s long-lasting formula protects against fleas through 6 weeks and is applied using a rounded tip applicator for comfortable, easy application. Cheristin comes in one dose size for all cats and kittens (1.8 lbs and greater or 8 weeks of age and older), making it great for families with multiple cats. Cheristin is available without a prescription.
Cheristin for Cats is a once-a-month topical solution specifically formulated for cats used to prevent and treat flea infestations.
Cats and kittens 8 weeks of age or older and weighing 1.8 lbs or greater
Cheristin® for cats kills fleas fast and is specifically designed for cats. While monthly application is recommended, a single dose of Cheristin kills adult fleas for up to 6 weeks. One size fits all*, which makes Cheristin ideal for households with multiple cats. Easy to apply: Quick-drying, non-greasy topical solution is gently delivered by a small applicator with a rounded tip. Fast: Starts killing fleas within 30 minutes and killed 98-100% of fleas within 12 hours in a controlled study. Convenient: Same low volume dose is gentle enough for all cats and kittens over 1.8 pounds and 8 weeks old. The active ingredient, spinetoram, received a 2008 Presidential Green Chemistry award for low environmental impact on the agricultural industry.
Spinetoram kills fleas in all stages of life safely and effectively
Monitor your cat after application. Side effects may include signs of application site reactions such as application site hair loss, hair change (greasy, clumping or matting) or redness, inflammation and itching. Other side effects such as inactivity, vomiting and inappetence have also been reported. If these or any other side effects occur, consult your veterinarian, your cat’s healthcare expert. For technical assistance or to report a side effect, call Elanco at 1-888-545-5973.

Have a big flea problem in Florida every year and we have many rescue cats in a cattery area. The cheap Amazon Basics cat flea products do nothing. Cheristin is more expensive but it works! Have not seen a flea since we started using it. Now we do half the cats each month and still seems to be working.

I have 2 indoor cats about 4 yrs ago we ended up with a flea infestation that was uncontrollable and very uncomfortable for us and the kitty's. After using everything imaginable and hundreds of dollars later. I didnt have a vet at the time due to a move. I just went into one by our house told them the situation and they said try cheristin. Within 30 minutes of applying it I could already see comfort in them. Within 4 hrs they finally were catching up on some over due sleep and looked so peaceful and this is hard to believe but by the next day not one flea on them. This medicine is a god send and I will never use anything other than this. Havent had a problem since. I plan on keeping it that way, couldn't believe how fast they multiply but I got rid of them suckers for good.

Gave this a try based on other reviews for an ongoing flea problem that Frontline and Advantix did not help. Southern fleas are a hardier breed than most and seem to consider other meds like a marinade. I have been using Cheristin for 3 months and consider it a miracle!!! No fleas on babies, no fleas on me, and no fleas in my home!!! I highly recommend this product.

This was recommended by a vet to us and validated by a different vet. Living in Florida, fleas are a real pain, especially when it doesn't get cold enough to kill off the fleas in the winter. One of our four cats occasionally escapes and goes for a walkabout. Since since using Cheristin for Cats, we not had any problems with fleas with our four cats.

Seems to work fairly well. Better than Advantage. Very oily though and cat does not appreciate the application. We'd use systemic med but every time we get a pill down her, she pukes it back up within 15 min.!

Deborah P Verified Purchase

Great Product. Works within 30 minutes. The fact of a tropical Flea resolver is great and I feel better that my kitty's are not getting Harsh Chemicals and hiw quick it works. Plus no Nasty Chemical smell and the cost us cheaper through Allivet then what my Vet charges. I HIGHLY RECOMMEND this product for your cats.

Robin b Verified Purchase

We live in Florida and have 2 cats that are never outside.Suddenly we were infested with fleas.No point trying to figure out if they jumped through screen in porch or were brought in on our feet etc.After bombing the house 2 0r 3 times and trying a lot of different spot treatment products to no avail whatsoever (which was extremely frustrating) I saw Cheristin and a lot of good reviews on it and the fact that it is relatively new on the market and made just for cats I thought why not try it. I am happy to say that it completely worked!!! I did have someone professional come to my house first and he sprayed, not bombed, the house but as soon as I put the Cheristin on my cats they have not had one flea and it has been 3 months so I am staying with it so this never happens again.GREAT STUFF and I highly recommend it!

Fleas where I live became tolerant to other flea products including Ceresto collars and the past two years have been a nightmare with flea combing and house bombing as my cats are indoor/outdoor cats. Cheristin worked from day one. Hopefully, the fleas don't grow tolerant to this product too soon!!!!

Elizabeth K Verified Purchase
October 19, 2017

My cats have been SUFFERING with fleas for months. NOTHING is working anymore. After years of Revolution and then moving to Advantage II, I was very disappointed that only capstar was giving them any relief. My vet said that the fleas were actually immune to the old topicals that I have always used. I took a chance on Cheristin and I really see an improvement in my cats behavior. No more constant biting and itching and even the flea allergy bumps are going away. I will continue to purchase this item.

Shelby O Verified Purchase
September 13, 2017

I have found that Cheristin works on fleas like nothing else. Maybe the fleas are getting stronger or building up a resistance to the other topical treatments. I haven't tried those popular (and expensive!) collars yet, because with 6 cats, that's very costly. But so far Cheristin has done the job. More expensive than other topicals, but worth it if it works, in my opinion.

Claudette P Verified Purchase

Laura W Verified Purchase
July 5, 2017

We have two indoor only cats and still got fleas! We attacked with a vengence, using veterinarian recommended products, including Advantage ll. For 5 very long weeks we vacuumed daily (including baseboards and furniture), hand washed all hardwood and linoleum daily, washed bedding daily, threw out all cat toys that could harbor fleas, removed a lot of furniture to make the process easier. We sprayed outside at least every two weeks, but still kept all doors and windows shut. We also sprayed Siphotrol or Knockout every week. We flea combed twice per day and the amount of fleas kept increasing. My pleading, frantic calls to the vet were patronized and unhelpful. Then, I called a different vet. They recommended Cheristin. We applied it last Friday and have not seen any live fleas on either cat. I'm just hoping it lasts, but finally feel we have our solution.

Shelley F Verified Purchase

This product works so good. My cats, three of them, are alergic to fleas. They get big sores on them and start to throw up all the time! When they take this wonderful medicine, sores start to heal, and they don't throw up all the time anymore. Five stars!!!!!!

It works! After trying several different brands this product actually killed the fleas in less than 24 hrs. No more fleas!

Susan P Verified Purchase

Works perfect for fleas. I exposed my kitty with another kitty who had fleas over a week after the application was given and when fleas jumped on him and took a bite they died. I never saw a live flea only the dead ones. Once they were gone they were gone!

Works especially well on by furry children who are hyper sensitive to fleas. Works longer than other medications and kills faster. also less irritating to them than other preps. usually able to find a discount coupon and the rebate from Elanco the manufacturer makes it an even better value.
