"Is This a Death Sentence?" The Honest Prognosis for a Diabetic Pet
It's the question really underneath all the others, even when no one says it out loud. An owner takes in the word diabetes, asks sensible things about insulin and diet, and behind their eyes is the thought they're too frightened to voice: is this it? Am I about to lose her? It's a fair thing...
Diabetes in Dogs and Cats: The Same Word, Two Different Diseases
When a dog or a cat is diagnosed as diabetic, most owners' minds reach straight for what they know about diabetes in people: a relative who injects insulin, a colleague who manages theirs with tablets and diet. Let me gently take that off the table, because the most useful thing I can tell you on...
Feline Diabetes Explained: Why a Cat's Diabetes Is Its Own Disease
Most of what gets written about pet diabetes carries, quietly, a canine accent. So if you've just been told your cat is diabetic, here is the thing worth knowing first: your cat's diabetes is not a smaller version of a dog's. It looks far more like human type 2 diabetes, and because the insulin-making cells...
Getting the Diagnosis: How Vets Confirm Diabetes
Most owners arrive at the diagnosis the same way. Something had been off for a few weeks: the water bowl emptying too fast, puddles where there had never been puddles, weight sliding off despite a hearty appetite. A sample went off, and now there's a word on the page. Let me walk you through how...
Can I Do This? The Honest Commitment of Caring for a Diabetic Pet
There's a particular silence that falls in the consult room after I say the word diabetes. The owner nods, asks a sensible question or two about insulin, and then, often while standing up to leave, comes the real one, the quiet one. "I work full time." "I'm not sure I'm the right person for this."...
What Diabetes Actually Is in Dogs and Cats
When I tell an owner their dog or cat has diabetes, I can see the same thing happen behind their eyes. They half-remember something about human diabetes, sugar, injections, and they're trying to map all of it onto the animal in front of them. Some have already decided it sounds like a death sentence. It...
Hypos: The Emergency Every Diabetic Owner Must Be Ready For
Of all the things I tell a new diabetic owner, this is the one I'd ask you to hold onto hardest. Most of the daily routine you're learning is forgiving: get the timing a bit off, run a little high for an afternoon, and your pet is fine. The one exception, and the reason this...
Your First Insulin Injection: How To Do It Without Fear
There's a moment I've come to recognise in the consult room. The owner has the diagnosis and the kit, they've nodded along to everything, and then I hand them a loaded syringe to try for the first time and their hand goes very still. They're not frightened for themselves. They're frightened of pushing a needle...
The First Two Weeks on Insulin: What To Expect
You're home from the vet with a little vial in the fridge, a box of tiny syringes, and a head full of half-remembered instructions. You've given the first injection, or you're about to, and the practical worry sits on top of a quieter question: how will I know if it's working? What if I'm getting...
Feeding a Diabetic Pet: Timing, Portions and Treats
Owners walk out of the diagnosis consult braced for the injections. Almost no one walks out worried about the bowl, and yet it's the bowl that trips most people up a fortnight later. What do I feed? How much? When, relative to the jab? Can he still have his bedtime biscuit? Feeding quietly does a...
Storing, Drawing Up and Handling Insulin Properly
There's a sentence I hear in the consult room more often than almost any other once a pet is a few months into treatment. "The insulin's stopped working." The dog is drinking again, the cat is losing weight, the readings have crept back up, and the obvious conclusion is that the dose has failed or...
The Insulin Types Explained (and the New Oral Options for Cats)
Most owners meet their pet's insulin as a single box pushed across the desk, a name they've never heard, with no sense of why that one. Then they search it and fall into forum threads arguing about Lantus versus ProZinc versus something they can't even buy here. So let me do what the leaflets and...
Continuous Glucose Monitors (FreeStyle Libre) on Pets: The Game-Changer
A few years ago, knowing what your diabetic pet's glucose did across a day meant grim choices: a row of finger or ear pricks at home, or a long, stressful day at the clinic having blood drawn every couple of hours. Then a small white disc designed for people with diabetes quietly changed everything. I...
Home Blood Glucose Monitoring: Curves and Spot-Checks, Done Properly
The first time most owners hear the words "blood glucose curve", the real question follows fast: you want me to take my pet's blood, at home, with a needle, every couple of hours? It sounds like something that should happen in a hospital.
Diet as a Lever: Low-Carb Cats, Consistent Dogs
Most owners arrive at the food question expecting me to hand over the name of a prescription diet and send them on their way. It's a fair expectation, but it sells the subject short. For a diabetic pet, food isn't only fuel. It's one of the levers we actually pull to change the disease, sitting...
Fructosamine and the Vet Rechecks: The Bigger Picture of Control
A few weeks into life with a diabetic pet, the rechecks start to feel like a ritual. You bring your dog or cat in, often with a phone full of home readings, the vet draws a little blood, weighs them, has a feel, and then talks about a number you may never have heard of:...
Reading a Glucose Curve: The Nadir, the Duration and Stress Hyperglycaemia
For most owners, a first glucose curve arrives as a column of numbers on a scrap of paper, or a wavy line on a phone app, and it can leave you feeling shut out of your own pet's care. Six readings, a squiggle, and the nagging sense that everyone but you knows which number matters....
How Insulin Dose Titration Works (and Why It Takes Weeks)
There's a question I can almost set my watch by. About two or three weeks after a pet starts insulin, the owner rings, and somewhere in the first minute it comes out: "I don't think the dose is right yet." Often there's a flicker of failure underneath it, as though they were meant to have...
The Lifetime Cost of a Diabetic Pet, and How Insurance Really Works
There's a moment, usually a day or two after the diagnosis, when the worry turns from your pet to your bank account. The leaflet says "diabetes is manageable," the forum says "it cost me a fortune," and nobody has given you the actual numbers. So let me lay them out plainly, because in twenty years...
Travel, Boarding and Sick-Day Rules for a Diabetic Pet
Diabetes settles, in the end, into a pleasant kind of dull. Two meals, two injections, a quick note in the app, twice a day, until it's muscle memory. And then one of three things happens. Your pet wakes up off their food. You've a holiday booked and a cool bag you're not sure how to...
Weight, Dental Disease and the Other Things That Quietly Wreck Control
There's a particular call I take more than any other from a settled diabetic family. The pet was doing well, the numbers had stopped sliding around, the dose hadn't changed in months. Then it all drifts: more water in the bowl, a litter tray needing doing twice as often, a morning glucose that creeps up...
Diabetic Cataracts in Dogs: Spotting and Managing the Blindness Risk
There's a phone call I take more than almost any other from owners of newly diagnosed diabetic dogs. The dog was fine. Then, over a weekend, the eyes went cloudy and the dog started bumping into the coffee table. The owner is frightened, and underneath the fright there's usually a flicker of guilt: did I...
What To Watch at Home: The Signs That Tell You How Control Is Going
In the early weeks, owners ask me a version of the same anxious question: "How do I know if it's working?" Behind it sits the assumption that the answer lives in a meter, that without a row of glucose numbers they're flying blind. The truth is more reassuring: the best monitoring tool you have is...
Settling Into the Daily Routine That Works
There's a moment, usually around the third or fourth week, when an owner rings the practice and I can hear that something has shifted. The panic has gone, the needle they were certain they could never manage has become a non-event done while the kettle boils, and the question is no longer "can I do...
Feline Diabetic Remission: Real, and the Window Is Now
When I tell an owner that their newly diagnosed cat might one day come off insulin altogether, I often watch the same thing happen on their face: hope, then a flicker of suspicion, because it sounds too good to be true. It isn't. Feline diabetic remission is real, common enough to be a genuine goal...
What "Good Control" Actually Looks Like (and Why It Isn't Perfect Numbers)
There's a particular worry I see in diabetic pet owners a few months in. The injections are happening, the pet seems well, and yet the owner is anxious, because they've been checking glucose at home, or reading a forum, and the numbers aren't "normal." Their own blood sugar would sit around 5 mmol/L. Their dog's...
What Good Control Buys: Heading Off the Complications
There comes a point, usually a few weeks in, when the injections and the meals and the logging stop being terrifying and turn into a chore. The fear fades, and what's left is the grind: two needles a day, every day, seemingly forever, for a pet who looks, frankly, fine. And a quiet question surfaces....
Staying in Remission, and Spotting a Relapse Early
There's a particular happiness I see in owners whose cat has just come off insulin. Relief, mostly, after weeks of injections and finger-pricks and worry. And then, usually in the same breath, a flicker of something else: but is it really gone? Will it come back?
Giving Your Cat the Best Shot at Remission: The Playbook
When an owner first hears that a cat, unlike a dog, can sometimes stop being diabetic, the next question is almost always the practical one. Not "is it true," but "what do I actually do?" The why and the biology live in feline diabetic remission, and I'd read that first if you haven't. This page...
Quality of Life and the Honest, Hard Decisions
The numbers won't settle no matter what you try. Or the cost has crept beyond what you planned. Or your pet is simply old, and you're starting to wonder whether you're holding on for them or for yourself. Whichever of those it is, let me start with what I'd say if you were sitting across...
Somogyi and Dose-Chasing: When More Insulin Is the Wrong Answer
There's a logic that feels unarguable when you're holding the meter. The number is high. Insulin brings numbers down. So surely the answer is more insulin. I've watched careful, loving owners follow that thread into trouble, nudging the dose up week after week because the morning reading stays stubbornly high. It's the most intuitive move...
When the Insulin Just Won't Work: The Resistance Work-Up
There's a sentence I hear when an owner has reached the end of their patience, and it always carries the same flat exhaustion. "We keep putting the dose up and it makes no difference." By then they've usually been climbing the dose for weeks, the numbers are still stubbornly high, and the fear underneath is...
Diabetic Ketoacidosis (DKA): The Emergency and Its Warning Signs
Diabetes can throw up two emergencies, and they run in opposite directions. One is the hypo: too much insulin, a blood sugar that crashes in minutes, the wobbly, trembling pet I write about in the hypoglycaemia guide. This page is about the other one, and it worries me more, because it's quieter at the start...
The Concurrent Diseases That Fight Your Insulin
The dose has crept up again. We're at numbers that would have sounded alarming three months ago, the glucose curve is still a flat high line that barely dips, and you're doing everything right. And yet the insulin just isn't working. The natural instinct, yours and sometimes mine, is to reach for the dial and...
The Unstable, Brittle Diabetic: Why Control Slips, and What To Do
There's a particular kind of tiredness I've learned to recognise across the consulting table, and it doesn't belong to the pet. It belongs to the person opposite: the one who's been up in the night checking the cat, who's turned down a weekend because nobody else can manage the injections, whose meter read 4 one...
