A weight loss drug for cats is being tested right now — and it might change everything.
Why Are So Many Cats Overweight?
Take a look around. Chances are, you know at least one very chonky cat. And you are not alone.
More than half of pet cats in the world are overweight or obese. In the United States, some estimates put that number as high as 60%.
A lot of it comes down to how we feed them. Many cats are “free fed” — meaning their bowl is always full and they eat whenever they want. Cats were not built for that. In the wild, they hunt small meals and move a lot. On the couch with unlimited kibble? Not so much.
We also love our cats, and food is a big part of that bond. Giving them a treat feels like giving them love. It is hard to say no to a cat who is staring at you.
What Happens to Cats Who Stay Overweight?
Being overweight is not just about looks. Extra weight causes real health problems for cats, including:
- Type 2 diabetes
- Joint pain and arthritis
- Heart and blood vessel problems
- Shorter lifespan
- A greasy, unkempt coat (overweight cats can’t reach to groom themselves)
Diabetes is especially serious. When a cat is diagnosed, owners often have to give insulin shots twice a day. Some owners are not able or willing to do that — and sadly, some cats are euthanized because of it.
Key Fact
About 80% of diabetic cats have Type 2 diabetes — the kind linked to weight and lifestyle. This is the same type that Ozempic was made to treat in humans.
What Is Ozempic, and Why Are We Talking About It for Cats?
Ozempic is a drug for humans that helps with weight loss and blood sugar control. It belongs to a group called GLP-1 receptor agonists. These drugs copy a natural hormone that your body releases after eating.
That hormone tells your brain: “You are full. Stop eating.” It also slows digestion and helps manage blood sugar.
Ozempic became very popular for human weight loss. It works well. Scientists started wondering — could it work in cats too?
It turns out the biology is very similar. The GLP-1 receptor that these drugs target is found in cats and humans alike. The body handles it in much the same way. That gave researchers a reason to try.
Who Is Behind the Cat Version?
A company called OKAVA Pharmaceuticals, based in San Francisco, is leading the charge. They developed a feline version of a GLP-1 drug called OKV-119. The clinical trial testing it has been nicknamed MEOW-1 — short for ManagEment of Over Weight cats.
The University of Florida (my alma mater) is also involved. Veterinary professor Dr. Chen Gilor is running a large pilot study that started in December 2025. About 50 obese cats are taking part.
THE GOAL: Help cats lose weight safely — and in doing so, prevent diabetes before it starts.
What Makes This Drug Different From a Regular Shot?
Here is the clever part. Anyone who has ever tried to give a cat a pill or a daily shot knows how that goes. It usually ends in scratch marks and hurt feelings — mostly yours.
OKV-119 is not a pill or a daily injection. It is a tiny implant — about the size of a microchip — that is placed just under the skin. It slowly releases the drug over six months.
That means:
- No daily pills
- No weekly vet visits for injections
- No stress for the cat (or you)
The drug used is called exenatide — the first GLP-1 drug ever approved for humans. It is different from semaglutide (Ozempic) or tirzepatide (Mounjaro), but it works the same way.
Is It Working?
Early results are promising. The trial is still in progress, but here is what we know so far:
- Cats getting the implant are losing weight.
- Cats in the placebo group (no drug) are not losing weight.
- No major safety concerns have been reported.
Full results from the pilot study are expected by summer 2026. That is when we will have a clearer picture of how well it works and whether there are any side effects.
Keep in mind: This is still early research. The drug is not available yet — and a lot more testing is needed before it could be sold to the public.
When Could Cats Actually Get This Drug?
If the trial goes well, the path forward looks like this:
- Summer 2026 — Full results from the pilot study
- 2026–2028 — Researchers apply for FDA approval and run larger studies
- 2028 — Possible commercial release (if all goes well)
The company hopes to price it at around $100 per month per cat. That is not cheap, but it is less than the cost of treating diabetes long-term.
After cats, OKAVA plans to study the drug in dogs as well.
Will This Replace Diet and Exercise for Cats?
No. And experts are clear about that.
GLP-1 drugs are a tool, not a magic fix. In humans, people who stop taking them often regain the weight. The same could happen in cats.
The big picture goal is to add a new option — not replace good feeding habits, portion control, and play time. Those things still matter.
The drug could be most helpful in cats who have not responded to lifestyle changes, or those at very high risk for diabetes.
What Does This Mean for Veterinary Medicine?
This is a big moment. For over a hundred years, the only tools vets had for obese pets were: feed less, move more. That is still true — but it does not always work.
A long-acting, targeted drug option could change how vets approach chronic weight problems in cats. It could also prevent a lot of suffering down the line.
It also shows a growing trend: using what works in human medicine and carefully adapting it for animals.
Bottom line: We are not there yet — but for the first time, vets may soon have a real medical tool to fight feline obesity. That is worth paying attention to.
