Yes — and this is the part that surprises most owners. Cats love the taste of whole salmon oil. Most CKD cats who refuse renal food, spit out capsules, and eat around powder supplements will finish a meal with Revillio on it the very first day. One pump on food they're already eating. No hiding, no fighting, no tricks.

Yes. Omega-3 supplementation for CKD cats is supported by peer-reviewed veterinary research. Our oil is sourced from Norwegian aquaculture under EU contaminant regulations and tested for heavy metals, PCBs, dioxins, and PFAS — critical for cats whose kidneys can't filter toxins efficiently. Start with a low dose, give with food, and consult your vet if your cat is on blood thinners or scheduled for surgery.

Pure Norwegian salmon oil and vitamin E. That's it. Whole, unprocessed, in its natural triglyceride form. The full fatty acid matrix stays intact — EPA, DHA, DPA, and natural astaxanthin. No fractionation, no ethyl esters, no anchovy or sardine blended in, no fillers, no artificial anything.

Yes. Revillio works alongside your cat's existing CKD protocol — renal diet, phosphate binders, sub-Q fluids, appetite stimulants. It doesn't replace any of them. It fills the gap none of them address: the inflammatory cascade that drives kidney disease progression. One pump on top of whatever your cat is already eating.

One pump per day, on food. That's it. Start with half a pump for the first few days if your cat has a sensitive stomach, then move to a full pump. Give it with a meal to maximize absorption. Takes less than ten seconds.

One bottle lasts approximately 30 days at one pump per day for a single cat. The bottle is sized specifically for cats — not a 32-ounce dog bottle where the last third goes rancid before your cat finishes it. Use within 90 days of opening. Refrigerate after opening for best freshness.

Most fish oils on Amazon are concentrated — chemically stripped down to isolated EPA and DHA in ethyl ester form. Your cat's body absorbs 50–70% less from ethyl esters than from the natural triglyceride form. They're also EPA-dominant (formulated for dogs) and packaged in oversized bottles that go rancid. A 2026 study found whole salmon oil delivered 4.3x more omega-3 absorption per milligram than concentrated alternatives. The big number on the label isn't what matters. What reaches your cat's body is.
