The cat who hides from fleas is often the same cat whose stomach protests at stress, travel, and every visit to the vet. This official bundle puts the full 6-dose Cheristin box in the same parcel as Pet Protect's Endurosyn probiotic gel — the flea half and the gut half of a nervous season, ordered once.

Directions & dose

The label, condensed

Part the fur at the base of the head, empty one full applicator onto the skin, and let it dry. That is the whole procedure — the table holds everything else worth knowing before you order.

The honest column

Side effects, read before you dose

What owners report most often

The label's most commonly reported reactions are local and cosmetic: hair loss, greasy or clumped fur, or mild redness and itching at the application spot. Less commonly, short-lived inactivity, vomiting or a skipped meal have been reported — typically resolving within a day or two.

The multi-cat grooming rule

Cats groom each other exactly where Cheristin goes. In multi-cat homes, keep housemates from grooming the treated spot until it is fully dry — dose everyone in the same sitting and supervise the first hour, or separate briefly.

When to call the vet

Marked lethargy past 48 hours, repeated vomiting, drooling, tremors, or anything that simply feels wrong for your cat — call your veterinarian, and have the box in hand; the label and lot number answer half their questions. Elanco also prints a product-support line on every carton.

Asked about this box

Before you click through

Longer answers live in the FAQ and the reading corner.

When does the gel earn its place?

Any week the routine breaks: a move, a new animal, a course of antibiotics, the carrier coming out of the closet. A pea of gel on the paw gets licked off before the protest starts.

Do the two products interact?

They don't meet — Cheristin goes on the skin at the base of the head, the gel goes in the mouth. Different routes, different jobs, same anxious cat.

Is the flea box in here the real thing?

Yes — the same 6-applicator retail box sold alone, bundled by Elanco's own Pet Protect line, not a repack.
