The weight loss drug revolution that has captivated human medicine may be heading to your cat’s veterinarian office.
San Francisco-based Okava Pharmaceuticals recently launched what they’re calling the MEOW-1 study, a clinical trial testing a GLP-1 drug delivery system specifically designed for cats. The timing feels significant when you consider that more than half of domestic cats in the United States are carrying excess weight, with many crossing into the territory of clinical obesity.
But before cat owners get excited about a pharmaceutical solution to feline weight problems, there’s much to unpack about what this research actually means and where it might lead.
What Makes This Different From Human Weight Loss Drugs?
The approach for cat weight loss differs from what humans experience with weekly Ozempic injections. Okava developed a tiny implant, only slightly larger than a microchip, that sits under a cat’s skin and slowly releases the medication over six months. The drug itself is exenatide, a different GLP-1 compound than the semaglutide found in Ozempic or the tirzepatide in Mounjaro.
The trial will monitor up to 50 cats, tracking their weight at three months while keeping them under evaluation for the full six-month period. This extended observation window matters because short-term weight loss often looks promising, but sustainability tells the real story.
Earlier research published in BMC Veterinary Research tested this technology on a smaller scale. Five cats received implants designed to release exenatide for 84 days, and four of them reduced their caloric intake and lost at least 5% of their body weight, maintaining that loss throughout a 112-day study period. One cat, notably the heaviest in the group, didn’t respond to the treatment at all.
Why didn’t that fifth cat lose weight? The researchers couldn’t say for certain. That uncertainty represents something important about this entire area of cat weight loss research. We’re still figuring out how these drugs work in feline biology.
How Would GLP-1 Drugs Change Cat Behavior?
GLP-1 drugs work by influencing appetite regulation and glucose metabolism. In humans, they slow stomach emptying and affect satiety centers in the brain. The assumption is they’ll do something similar in cats, but cats aren’t just small, furry humans.
Okava claims that cat owners should expect behavioral changes, including reduced food motivation, less begging, decreased scavenging, and better portion control. They also anticipate cats becoming more active and energetic as weight comes off.
But here’s where things get complicated. Anyone who has lived with a cat knows that food often forms the foundation of the human-cat relationship. Training relies on treats. Bonding happens over meals. That enthusiastic meow when you open a can of food represents one of the most reliable ways cats show affection and engagement with their owners.
What happens to that relationship when a cat becomes less food-motivated? A previous cat weight loss drug for dogs, Slentrol, was pulled from the market partly because owners disliked how it changed their pets’ relationship with food. According to veterinary endocrinologist Dr. Andrew Bugbee at Texas A&M, some veterinarians have already begun using human GLP-1 drugs off-label for diabetic cats, though high costs and limited effectiveness, especially in advanced cases, remain challenges.
What Are the Real Stakes for Cat Health?
The obesity statistics in pets mirror disturbing trends in human populations. Over 50% of domestic household cats are overweight or clinically obese, creating genuine health concerns that go beyond aesthetics.
Excess weight in cats correlates with diabetes, joint problems, and reduced lifespan. Diabetic cats typically require twice-daily insulin injections, an expensive and time-consuming treatment that many owners struggle to maintain. Many diabetic pets end up euthanized within a year of diagnosis, partly because the treatment demands prove overwhelming.
Could a six-month implant that helps manage both weight and glucose metabolism offer a better path? Possibly. The earlier research showed promise not just for cat weight loss but for addressing the metabolic dysfunction that leads to diabetes in the first place.
But calling this a solution would be premature. The current trial needs to demonstrate safety and efficacy in a larger group of cats before anyone can draw firm conclusions. Even then, the path from successful trial to veterinary clinics involves extensive additional testing and FDA approval, which Okava hopes to pursue between 2027 and 2028.
What About Cost and Access?
The target price sits around $100 per month, roughly comparable to premium cat food. For some cat owners, especially those already facing potential diabetes management costs, that might seem reasonable. For others, it represents yet another expense in an increasingly costly realm of pet ownership.
The pricing also raises questions about equity in pet care. If these drugs prove effective, will they primarily benefit cats whose owners can afford them, while cats in lower-income households continue suffering from obesity-related health problems?
Human GLP-1 drugs have created supply chain issues and access problems. Demand has occasionally threatened availability for diabetics, the population these drugs were originally designed to help. Adding pets to the equation could complicate that situation further.

Should Cat Owners Be Thinking About This Now?
Not really. The MEOW-1 trial represents early-stage research. Results won’t be available until next summer at the earliest, and even positive results would require years of additional testing before any product reaches the market.
What cat owners should be thinking about is the same thing veterinarians have been emphasizing for years. Cat weight loss through controlled feeding, appropriate portion sizes, and increased activity remains the foundation of feline health. These traditional approaches don’t carry unknown risks, don’t require FDA approval, and don’t cost $100 a month.
Could pharmaceutical interventions eventually offer valuable tools for managing feline obesity? Possibly. The research certainly merits attention and continued study. But declaring this a breakthrough would be getting ahead of what the science actually shows right now.
The questions raised by this research extend beyond whether a drug can make cats lose weight. How do we balance the medical benefits against potential changes in behavior and quality of life? What happens to the human-animal bond when food becomes less central to that relationship? How do we ensure that pharmaceutical solutions don’t become substitutes for fundamental changes in how we feed and care for our pets?
These aren’t simple questions. They don’t have obvious answers. And they’re worth serious consideration as this research moves forward.
