Some cats can take a veterinarian-prescribed oral diabetes medicine instead of insulin shots, but only if they meet strict health criteria. Diet alone is not a dependable substitute for treatment. In the United States, the oral medicines Bexacat and Senvelgo are intended for otherwise healthy cats that have never received insulin. They can cause life-threatening ketoacidosis, so a veterinarian must decide whether one is appropriate and arrange monitoring.
Is there a pill or oral medicine for cat diabetes?
Yes. In the United States, the FDA has approved two once-daily oral SGLT2 inhibitors for certain cats: Bexacat (bexagliflozin), a flavored tablet, and Senvelgo (velagliflozin), an oral solution. These medicines lower blood glucose by increasing the amount of glucose excreted through the kidneys. FDA approval and product availability are U.S.-specific; owners elsewhere should ask a local veterinarian about approved options and prescribing rules.

They are not interchangeable with insulin for every cat. The FDA says these medicines are for otherwise healthy diabetic cats that have not previously received insulin. A cat that has received insulin, or whose diabetes requires insulin, should not be switched to either drug. Do not stop insulin, reduce its dose, or start a leftover or human medicine without the prescribing veterinarian.
Which cats may be candidates for oral treatment?
A veterinarian needs to assess the diagnosis, health status, and treatment risks before prescribing an SGLT2 inhibitor. AAHA’s 2026 diabetes guidelines emphasize that not every cat is a suitable candidate. Diabetes diagnosis itself should be based on sustained high blood glucose, not a single reading that may be affected by stress.

The FDA’s Bexacat and Senvelgo guidance warns against starting treatment in a cat that is not eating well, is dehydrated, or is lethargic. Kidney, liver, pancreatic disease and ketones are among the findings that may affect eligibility; the veterinarian determines what screening is needed. A cat’s prior insulin use is especially important: these drugs should not be used as a do-it-yourself replacement for insulin.
What are the risks of Bexacat and Senvelgo?
The most serious concern is diabetic ketoacidosis (DKA), including euglycemic DKA, a dangerous complication that can occur without a high blood glucose reading. A reassuring meter number does not rule it out. FDA warnings describe ketoacidosis as potentially life-threatening, and warn that moving a cat from insulin to either SGLT2 medicine can lead to severe outcomes.

If a cat taking one of these medicines stops eating, becomes lethargic or dehydrated, loses weight, vomits, or otherwise seems ill, contact a veterinarian promptly and follow the medicine-specific emergency plan. Do not wait for a high glucose reading or try to manage the problem by changing the dose yourself.

For Bexacat, the FDA figure came from two six-month field studies and an extended-use field study; for Senvelgo, the FDA reported it for a six-month field study. Those study results do not predict an individual cat’s response or remove the need for careful selection and follow-up.

Can diet alone control a cat’s diabetes?
Diet and weight management are important parts of diabetic care, but diet is usually complementary to insulin or an SGLT2 inhibitor. AAHA says remission after diet change alone sometimes occurs, but it is not an expected outcome. A high-protein, low-carbohydrate diet combined with insulin has been associated with reported remission rates ranging from 15% to 100% across studies; that wide range reflects differences between studies and is not an individual forecast.
Work with the veterinarian on a food plan that supports reliable intake of a complete and balanced diet, appropriate calorie and portion control, and any other health needs. Canned foods can be useful for lower carbohydrate levels and portion control, but no single prescription food is right for every diabetic cat; concurrent illnesses can affect the choice.

What does diabetic remission mean?
AAHA defines remission as normal blood glucose maintained for more than four weeks without insulin or oral hypoglycemic drugs. It is not a cure: relapse is common, so cats in remission still need follow-up and attention to weight and clinical signs.

Among cats that achieved remission, approximately 25% did so in the two to three months after diagnosis, and a majority did so within six months. These timing figures describe cats that achieved remission, not all cats diagnosed with diabetes.

How are treatment and remission monitored?
Glucose readings are one part of assessment; appetite, thirst, urination, weight, energy, and overall response also matter. A veterinarian may recommend home blood glucose monitoring or a continuous glucose monitor (CGM) as part of a care plan. A device does not replace diagnosis or veterinary interpretation. AAHA notes that a low reading from a human-calibrated CGM may not accurately represent a cat’s blood glucose and may need to be checked against a veterinary-calibrated meter and the cat’s clinical signs.
Monitoring is important for cats receiving insulin as well as those considered for oral treatment. Insulin-treated cats can enter remission without obvious signs; if remission goes unnoticed, continued insulin can cause potentially life-threatening hypoglycemia. Ask the veterinarian how and when to check glucose and what readings or symptoms require a call.
How should you discuss avoiding injections with your veterinarian?
If injections are difficult for you or your cat, tell the veterinarian rather than changing treatment on your own. Ask whether the cat has ever received insulin, whether an oral medicine is locally approved and appropriate, what screening is needed, and what monitoring and emergency plan would apply. The 2025 iCatCare consensus likewise treats treatment choice as an individual assessment involving the cat’s other conditions, the caregiver’s needs, diet, and a workable monitoring plan.
Insulin remains an important treatment for cats that need it. Choosing between insulin, an oral medicine, and supportive dietary care depends on the cat’s diagnosis and eligibility, health findings, and the risks and monitoring each option requires—not simply on which route seems easier.
