If your cat was diagnosed with diabetes this year, the treatment your vet recommends might look nothing like what a friend’s diabetic cat received two or three years ago. That’s not inconsistency. That’s the field actually moving. On April 27, 2026, the American Animal Hospital Association published its first-ever feline-specific diabetes guidelines, and the central shift is bigger than most pet owners realize: for many newly diagnosed cats, a daily pill or oral solution now comes before insulin in the treatment hierarchy. After 13 years watching diabetes management evolve in clinic, I’ll be honest, I didn’t expect an oral medication to leapfrog insulin this decisively in formal guidelines. But here we are, and if your cat is diabetic or you’re watching a chunky middle-aged cat show suspicious signs, you need to understand what changed and why.

Why Separating Cats From Dogs Was Long Overdue

For years, AAHA published combined canine and feline diabetes guidelines. Vets working from those documents had to mentally filter recommendations by species, which sounds manageable until you realize how differently diabetes actually behaves in cats versus dogs. Feline diabetes has a meaningful chance of remission if caught early and managed aggressively. Canine diabetes essentially never goes into remission. Those two realities demand genuinely different protocols, not a shared document with footnotes.

The 2026 guidelines, published simultaneously in the Journal of the American Animal Hospital Association on May 1, 2026, are the first time AAHA has built a framework specifically around how cat physiology works. That distinction matters for every recommendation in the document, from which drug to reach for first, to how blood glucose should actually be measured.

Here’s the part that will genuinely surprise cat owners who’ve been in the diabetes trenches for a few years. Two oral medications, bexagliflozin (brand name Bexacat, a tablet) and velagliflozin (Senvelgo, an oral solution), are now the recommended starting point for many newly diagnosed diabetic cats. Bexacat has been FDA-approved since late 2022, Senvelgo since 2023, so these aren’t brand-new drugs. What’s new is their formal elevation to first-line status over insulin.

SGLT2 inhibitors work by blocking glucose reabsorption in the kidneys, essentially causing the cat to excrete excess blood sugar in urine. For an owner, the practical appeal is obvious: giving a cat a pill or squirting a small volume of liquid into their mouth is dramatically less stressful than twice-daily insulin injections, which require handling a syringe, maintaining cold storage, and timing meals precisely. What surprised me when I dug into the dvm360 coverage from June 2026 was the frank acknowledgment from task force experts that many general practitioners are still uncomfortable or even afraid to prescribe SGLT2 inhibitors despite their multi-year availability. That hesitation in the vet community makes owner education especially important right now. If you’re newly diagnosed, you have every reason to ask your vet whether your cat is a candidate.

Who Cannot Use These Oral Medications

This is where I want to be very direct, because the safety profile matters enormously here. SGLT2 inhibitors are not appropriate for every diabetic cat, and the guidelines are specific about who must go straight to insulin instead.

Cats who are vomiting, lethargic, have a poor appetite, or are presenting as generally unwell at diagnosis are not candidates. Cats with advanced kidney disease (IRIS Stage 3 or higher) or significant liver disease should not receive these medications either. The AVMA’s May 2026 coverage of the guidelines emphasized that appropriate patient selection is central to using this drug class safely.

The safety concern I want every owner to understand is something called euglycemic diabetic ketoacidosis, or EDKA. Standard DKA, which is a life-threatening emergency, is typically associated with very high blood glucose readings. Euglycemic DKA is dangerous precisely because blood glucose can appear normal while ketones are dangerously elevated. The 2026 guidelines flag this as a real risk with SGLT2 inhibitors and make blood BHB (beta-hydroxybutyrate, a ketone marker) monitoring an essential part of management. If your cat is on Bexacat or Senvelgo and starts vomiting, becomes lethargic, or stops eating, do not wait and watch. That’s an emergency-level presentation regardless of what their glucose meter reads at home.

How Monitoring Has Changed: CGMs In, Hospital Curves Out

The monitoring section of these guidelines represents a meaningful shift in day-to-day management. Traditional in-hospital blood glucose curves, where your cat spends a chunk of the day at the clinic getting serial glucose readings, are no longer recommended by the new framework. If you’ve ever dropped your cat off for a curve and gotten back a nervous, food-refusing, stress-hyperglycemic data set that told your vet almost nothing useful, this will not shock you.

What the guidelines push toward instead is at-home continuous glucose monitoring using CGM devices. Human CGM sensors like the FreeStyle Libre have been used off-label in cats for several years, and the data quality from a cat lounging at home is simply more representative than readings from a stressed cat in a clinic. For owners willing to learn the technique of applying and reading a CGM, this represents a genuine upgrade in how closely you can track glucose trends over days and weeks, not just a single point-in-time hospital visit. It takes some learning, and not every owner will feel confident doing it, but the guidelines are clearly encouraging this direction.

What to Do With This Information Right Now

If your cat was diagnosed with diabetes in the past few months and is currently on insulin, that doesn’t mean your vet made a mistake. Insulin remains entirely appropriate for many cats, including all the patients who don’t qualify for SGLT2 inhibitors. But it’s reasonable to have a conversation about whether your cat’s current protocol aligns with the 2026 guidelines, especially if your cat is otherwise healthy and doing well on current management.

If you have a newly diagnosed cat and your vet hasn’t mentioned bexagliflozin or velagliflozin, ask about them directly. Not every general practice has updated their protocols yet, and the task force that authored these guidelines essentially said as much. Bring up the April 2026 AAHA guidelines by name if you need to. A good vet will welcome the conversation.

If your cat is showing signs that could be diabetes, including increased thirst, increased urination, weight loss despite a good appetite, and hindlimb weakness, get them seen promptly. Early diagnosis opens more treatment options, including the possibility of remission in cats who respond well to aggressive early management.

The field genuinely moved this spring. For cats and the people who love them, that’s a good thing worth knowing about.
