Meowzempic: Why GLP-1 Drugs Could Be Coming for Your Cat's Waistline

Your chonky cat is a real health story, not just a meme

Round, "chonky" cats go viral constantly, and it's easy to laugh along. But the underlying issue is serious: roughly 61% of cats and 59% of dogs in the U.S. are overweight or carrying obesity, according to the Association for Pet Obesity Prevention. Excess weight in cats raises the risk of arthritis, diabetes, and a shorter, lower-quality life. That's the real backdrop behind a story that's suddenly everywhere: GLP-1 drugs, the same class behind Ozempic and Zepbound in humans, are now in actual clinical trials for cats.

The trial making headlines

San Francisco-based Okava Pharmaceuticals recently dosed the first cat in its MEOW-1 clinical trial — 50 cats testing a tiny under-the-skin implant called OKV-119. Inserted during a normal vet visit, the implant slowly releases a GLP-1 medication over roughly six months.

"In veterinary medicine for the last 100 years, the only prescription we had was feed less, exercise more, and that just doesn't work for all types of obesity," said Dr. Ernie Ward, a veterinary obesity expert involved with the trial. Okava CEO Michael Klotsman described the goal as mimicking "many of the physiological effects of fasting — improved insulin sensitivity, reduced fat mass, and more efficient energy metabolism — without requiring significant changes in feeding routines or disrupting the human-animal bond that often centers around food."

Why an implant, not a pill or a stricter diet

Anyone who's tried to put a cat on a strict diet knows the friction it creates at home — cats beg, meow, and food is often how owners bond with them. An implant sidesteps the daily behavioral battle entirely, and unlike a pill, there's no risk of a cat simply refusing to take it.

Okava isn't the only one racing here

Cornell University's College of Veterinary Medicine is separately running a clinical trial of AKS-562c, a once-weekly injectable GLP-1 Fc-fusion candidate from Akston Biosciences, also targeting weight loss in overweight and obese cats. Two different companies, two different drug delivery approaches, both chasing the same problem — a strong signal this isn't a one-off experiment but the start of an actual new veterinary drug category.

The critical distinction: a supervised trial is not your own Ozempic prescription

This is the part that matters most for pet owners right now: no GLP-1 drug is currently approved for veterinary use in cats or dogs. Veterinary and animal-safety organizations have separately flagged a rise in pets accidentally getting into owners' human GLP-1 medications like Ozempic, Wegovy, or Mounjaro — and that is a genuine poisoning risk, not a shortcut to the same benefit. Pets metabolize these drugs differently than people do, dosing for a 12-pound cat is nothing like dosing for an adult human, and there is no supervision, monitoring, or safety data behind giving a pet your own prescription. The MEOW-1 and Cornell trials are working through proper veterinary drug development for exactly this reason.

Timeline, cost, and what happens next

Results from the MEOW-1 trial are expected as soon as this coming year. If the data holds up, Okava has said it intends to seek FDA approval for cat use within about two years, with a dog version to follow. The company has floated a rough target price around $100 per month for owners — though that, like everything else here, is subject to change based on trial outcomes and the FDA approval process.

What this means if you have an overweight cat or dog right now

• There's no approved GLP-1 option yet — anything you see marketed as one today for pets isn't a legitimate, tested product.
• Never share your own GLP-1 medication with your pet. This is a real and rising cause of accidental pet poisoning, not a way to get ahead of an approval that hasn't happened.
• Weight management still matters today, with the tools that already exist — your vet can help build a real plan (diet, activity, medical workup for underlying causes) rather than waiting on a drug that's still years from your pharmacy.
• Ask your vet about clinical trial enrollment if you're interested and your cat qualifies — that's the legitimate way to access this kind of treatment before approval, under real medical supervision.
