Cheristin Flea Treatment & Prevention for Cats | Fast acting topical flea treatment for cats over 1.8 lbs | 6 Count

This works very well. When I looked into this chemical, I found it originated in Japan. With the amount of flea spray they use around these parts, the fleas don't seem to die. They may even think it is fertilizer! I put this on my cat and he stopped the itching quickly as the fleas died. The different chemical kicked the fleas buttocks. They had no tolerance built up against this treatment. Easy application on back of head with drops. There used to be a sticker to put on calendar as a reminder to reapply. Maybe they still have that nice little feature. I notice there are options for 1,3,6 applications. They might even have a 12 pack. Worth the money from my experience.

If you’ve ever battled fleas in the southern U.S., particularly in Georgia, you know those little pests don’t play fair. I swear the fleas here are built different—stronger, sneakier, and somehow immune to most over-the-counter treatments. Enter: Cheristin, the only thing that’s finally given both me and my cat a break. My 5-year-old, 9.3-pound, formerly feral ginger cat who once lived under my house and slowly (over the course of a year) decided I was trustworthy enough to accept cuddles and full-time indoor luxury. He has a catio for safe outdoor time—he’s earned his spoiled status. Outside time = fleas. We tried shampoos, natural sprays, and the kind of expensive spot-ons that come with a dissertation-length warning label. Nothing worked and kept him feeling okay—until Cheristin. Here’s what stood out immediately: 🕒 Fast-Acting Relief This stuff starts working in 30 minutes and lives up to the hype. Within a few hours, I noticed a dramatic reduction in scratching and the flea “sightings” (aka when he runs across the room like something’s biting his soul). 💥 Kills Fleas Dead—Fast The claims say 98–100% flea kill within 12 hours. I believe it. By the next morning, it was like the fleas had packed up and left town. No scratching, no twitching, no more flea comb drama. 🧴 Easy Application The applicator has a small rounded tip that makes it easy to apply right between the shoulder blades—aka the “zone of tolerance” for most cats. My guy barely noticed. No greasy residue, no strong smell, no weird side effects. 🌿 No Nausea or Weird Reactions Some treatments have made him lethargic or nauseated in the past. Not this one. He went back to sunbathing like a king and zooming around the house without missing a beat. 🙌 Multi-Cat Friendly While I just have the one, I appreciate that Cheristin comes in a one-size-fits-all dose. If you’re managing a pride of cats, this is so much easier than juggling sizes and labels. A few helpful tips: - Apply at night so it has time to fully absorb before your cat resumes back-flip grooming. - One dose truly lasts the full 6 weeks—though I set a calendar reminder at 5 weeks because Georgia fleas are relentless. - Works even with cats who spend time outdoors (in controlled settings like catios or screened porches). In short, Cheristin saved my sanity and let my spicy little ginger boy enjoy his catio time again—flea-free and fabulous. If you’re at your wit’s end and nothing else has worked, give this a try. Your cat deserves comfort, and let’s be real—so do you.

This product is super safe for older cats and fleas gone within 12 hours just as it says! This was the best product with no side effects for my 15yr old little lady! And affordable.

Great product! Cheristin got rid of the fleas from my two cats! I have tried the other competing name brand companies and none of them seem to get rid of my flea problem. I believe the fleas in my area (I live in California) became resistant to the formulas of the competing companies. Cheristin is very easy to use. All you have to do is twist the cap to open and it’s ready to use. It only needs to be applied once a month and works on both kittens and cats. The only reason I give this product 4 stars is that this product does have a VERY strong and unpleasant smell. It smells moldy and the smell will last for days. The product also leaves a greasy residue that also lingers for a few days. Other than the smell and residue I will say this is a very effective product.

Immediate effect on both my cats, noticed they stopped scratching & it provided them with a relaxed mood. I like that it’s easy to apply & with applying at the back of the neck they cannot lick. Smell is fairly pleasant 👍

Worked so quickly! Will purchase again in the future. Worth the money!! Literally killed them within 30 min and you can see the dead fleas on their fur.

It works so good. I have a girl cat that has had fleas. She has bitten so much her fur is bald in patches. We have tried natural things that didn't work. My vet recommended this because their appts were out for 3 months. The first hour we put this on (Jane) she stopped itching a lot. By the second day she had almost stopped. I would recommend this to anyone who wants their cats to be happy.
