What's inside
Whole Norwegian salmon oil — nothing stripped, nothing added
Pure Norwegian salmon oil
Whole, unprocessed oil in natural triglyceride form — absorbed 4.3x more effectively than concentrated alternatives
Vitamin E
Essential antioxidant that prevents steatitis and protects the omega-3s from oxidation — most fish oils skip it
Omega-3 fatty acids
Natural DHA-dominant ratio — the ratio cats actually need, unlike dog-formulated EPA-heavy concentrates
Omega-6 fatty acids
Balanced ratio to support healthy skin barrier and coat — works with omega-3s to regulate the inflammatory response
DHA
Supports kidney function, brain health, and cognitive sharpness — the omega-3 cats need most, especially seniors
EPA
Primary anti-inflammatory — reduces joint stiffness, supports heart health, and interrupts the inflammatory cascade in CKD
Natural astaxanthin
The antioxidant that makes salmon pink — protects kidney tissue from oxidative damage. Absent from anchovy and sardine oils entirely
DPA reservoir
The third omega-3 that converts into EPA or DHA on demand — destroyed during concentration, preserved in whole oil
Sourced and tested
Most fish oils strip everything out to put a big number on the label. Revillio keeps the full matrix intact — the way your cat's body was designed to absorb it.
A 2026 clinical study found whole salmon oil raised omega-3 blood levels 4.3x more effectively than concentrated alternatives — despite a lower number on the label.
Cats need more DHA than EPA — the opposite of dogs. Norwegian salmon oil naturally delivers the DHA-dominant ratio your cat's kidneys and brain actually require.
DPA, astaxanthin, phospholipids, and the complete fatty acid profile — all preserved. Concentrated oils destroy everything except isolated EPA and DHA during processing.
No pills to hide. No powder that changes the taste. One pump on food they're already eating — the only part of their routine they actually look forward to.
The science behind Revillio isn't marketing — it's published feline medicine.
Not all fish oil is the same. Here's why the cheap bottle on Amazon isn't doing anything for your cat.

From CKD management to coat recovery — real results from real cats.
"His creatinine stopped climbing for the first time in two years. My vet looked at the bloodwork and asked what changed. He finishes every meal now. I forgot what that looked like."
"Her coat grew back fuller and softer than it's been in years. She's grooming herself again. Both my CKD seniors gained weight after I switched to Revillio. I was so close to giving up."
"He's 17 now and still jumping on the counter. This is the one thing in his entire CKD routine he actually wants. No fighting, no hiding pills. He hears the pump and comes running."
Results from consistent daily use of whole Norwegian salmon oil
Cat finishes the bowl — no coaxing, no syringe, no tuna water tricks
Weight starts coming back — first time the scale moves in the right direction
Coat visibly thicker and softer — cat begins grooming again on their own
Kidney values stabilize — creatinine stops climbing, vet confirms improvement
