Cheristin Cat Flea Treatment, 6-Count Topical Doses for Fast-Acting Protection

Cheristin is a prescription-free topical flea treatment for cats, designed to kill fleas with a low-volume dose applied to the skin.

• Begins killing fleas in 30 minutes — starts acting soon after application.
• Kills 98%–100% of fleas within 12 hours — provides a defined fast-acting result.
• Protection lasts through 6 weeks — helps provide ongoing flea protection after a dose.
• Non-greasy, quick-drying formula — fits a topical application routine.
• Rounded-tip applicator — delivers the dose directly to the skin.

Flea treatment needs can be more complicated in a household with cats of different sizes. Cheristin is made for cats and kittens that meet its age and weight requirements, with one dose size for that eligible group. Its topical format is applied at the base of the cat’s head, making the product relevant for cat owners looking for an at-home flea treatment rather than a treatment that requires a prescription.

How quickly does Cheristin start killing fleas?

Cheristin starts killing fleas in 30 minutes, and kills 98%–100% of fleas within 12 hours. Its fast-acting flea-killing performance is also stated to work faster than Frontline Plus and Advantage II. Protection continues through 6 weeks, giving the dose a longer period of flea protection beyond the initial kill window.

• Topical application places the treatment on the skin.
• The flea-killing timeline begins after application.

Which cats can use Cheristin?

Cheristin is for cats and kittens weighing at least 1.8 lb (0.82 kg) and aged 8 weeks or older. Its low-volume, one-size dose is intended for all cats that meet both requirements, so multi-cat households can use the same product across eligible cats without managing different product sizes.

• Suitable for kittens as well as adult cats that meet the age and weight thresholds.
• Each cat must meet both the minimum weight and minimum age.

How do you apply the six-dose pack?

The pack contains six single doses in small applicator tubes. To apply one dose, hold the tube upright and twist the nozzle tip to open it. Part the hair at the base of the cat’s head until the skin is visible, then place the open tip directly above the skin and squeeze the tube 2–4 times to expel its contents. Discard the empty tube after use.

The rounded tip is designed to make the dose easy to apply, while the non-greasy formula dries quickly. Apply the contents onto the skin rather than the hair so the topical treatment is placed at the intended application site. Each tube is a single dose, and the six-count pack provides six applications.

• Open the tube by twisting the nozzle tip.
• Part the hair until the skin is visible before applying.
• Squeeze 2–4 times to release the tube contents.

Cheristin suits cat owners seeking a prescription-free topical flea treatment, particularly households with multiple cats that meet the same age and weight requirements. It is intended for cats and kittens at least 8 weeks old and weighing at least 1.8 lb (0.82 kg); the six-dose pack contains single-use applicators for those eligible cats.
