Curiosity, answered

Curiosity gets a bad name from one proverb. Around here it gets answers instead — the questions cat people actually bring to a flea page, grouped the way they arrive.

Buying the box

Where does the purchase happen? On Amazon, start to finish. Every button opens the matching listing; the box, the payment and the porch delivery all live there.

Why doesn't your price always match the listing? Amazon reprices around the clock and a shelf can't chase it minute by minute. The price at checkout is the real one.

Three doses or six? Three to prove the product to a skeptical household, six to stop thinking about fleas until winter. The 6-pack costs less per dose — the full math lives in the reading corner.

Using the drops

How fast does it work? Fleas start dying about 30 minutes after the drop lands; 98–100% of adult fleas are gone within 12 hours.

Monthly or every six weeks? One dose protects through six weeks, but a fixed monthly date is the rhythm that never drifts into a gap.

Does it kill ticks? No — Cheristin is a dedicated flea product. If ticks patrol your area, ask your vet what to pair with it.

Cats, kittens and everyone else

Is it safe for kittens? From 8 weeks of age and 1.8 pounds of weight — both lines together, exactly as the label draws them. The kitten guide walks the details.

Can my small dog borrow a dose? No. Cheristin is formulated for cats only, and species lines on flea products are not suggestions in either direction.

Why do all pack sizes show the same 22,264 reviews? Amazon pools ratings across a product's variations, so the count belongs to the whole line — whichever box comes home.
