House rules for humans
Every household with a cat already runs on rules nobody wrote down: the warm chair is taken, the fur is final, dinner is at five. The ones below are the written kind — short, and in daylight.
The shelf and the till
This site is Cheristin's shelf: the boxes, the label read out in plain light, the guides. The till is Amazon's. Every buying button opens the matching Amazon listing, and from that click onward — price, stock, payment, delivery, returns — you are in Amazon's house, under Amazon's rules.
Prices are weather
We copy prices onto the shelf the way a windowsill records the sun — accurately at the time, with no power over what happens next. Amazon reprices continuously; where our figure and the listing disagree, the listing is right and we are a little out of date.
The vet outranks this website
Everything here is drawn from the product label and written with care, and none of it is veterinary advice. For your particular cat — the one with the history, the weight, the opinions — your veterinarian has the final word over any page on the internet, including these.
The names on the boxes
Cheristin® and Pet Protect™ belong to Elanco and its family of brands. We keep this shelf tidy in their honor and send every purchase to the official listings.
