   A vet reviewed thirteen guides, and then we edited all thirteen of them

   Dr Linda Simon read the app and thirteen guides on 24 October 2026. Within a day every one of those pages had been edited — mostly by us, several substantially. The life-expectancy figures were rewritten completely after a source check found they came from nowhere; the hypoglycaemia page had its emergency instructions restructured; the treats page had a tip of hers reframed because the guideline position turned out to be narrower than we had written it. She has not seen any of the current versions, and this was a single paid engagement rather than a retainer, so we have no standing arrangement for her to. Leaving her byline sitting over text she never read would have been the easy thing and the dishonest one. Each of those pages now records a fingerprint of itself as she read it, the site compares that against the page on every build, and any page that has changed says so beside her name. Nobody has to remember to do it: the next edit to a reviewed page changes the claim automatically, whether or not the person making it thought about this. What she found and what we changed because of it still stands — the review was real and it made the site better. What we cannot claim is that she has read what is there now.

   Our life-expectancy figures were not from anywhere

   The page on how long a diabetic pet lives said that most diabetic dogs live 2 to 5 years after diagnosis, that cats live comparably, and that 60 to 70 per cent of newly diagnosed cats reach remission in the first year. We cannot source any of those figures, and the published data points elsewhere. The largest UK primary-care study of diabetic dogs found a median survival of 15.6 months from diagnosis; the equivalent feline study found a median of 68 days. The 2026 AAHA guidelines work to a remission rate of about 30 per cent, and the reported range across studies is 11 per cent to just over 60 per cent — so our 60 to 70 was at the top of the range, presented as the typical case. The page now gives the real figures with the context they need: both UK medians are dominated by animals euthanased at or within days of diagnosis, many never treated, so they describe a population rather than a prognosis. That is a harder page to write and a more useful one to read. Because the numbers changed, the page needs looking at again by the vet who reviewed it.

   We said good glucose control prevents cataracts. It does not

   The complications section listed "Prevention: good blood glucose control" under diabetic cataracts. The specialist ophthalmology reference is explicit that cataracts occur in over 85 per cent of diabetic dogs regardless of how well the diabetes is regulated. Telling an owner that control prevents them is not only wrong, it hands them a reason to blame themselves when their dog goes cloudy-eyed anyway. The page now says plainly that a cataract is not evidence you have managed the diabetes badly. We also removed a cataract surgery cost quoted in US dollars on a UK site, for which we had no source at all.

4. 25 October 2026

   Four smaller claims the evidence does not support

   A source check across eight guides turned up four more. We said remission is impossible in dogs; it is rare, but a season-driven diabetes in an entire bitch can resolve after spaying, which is why vets ask. We said cats who reach remission typically do so within 4 to 12 weeks; about a quarter do, and most of the rest take up to six months. We gave a carbohydrate target of "under 10%" with no units, which on a label would read as dry matter and set a stricter target than any guideline states — that page now points at the feeding guide, which shows the working. And we stated as general advice that a treat given after a meal is covered by that meal’s insulin; that is a practising vet’s tip rather than a guideline position, and it now reads as one, with the sourceable point — consistency of timing and amount — leading instead.

5. 25 October 2026

   We named a medicine that does not exist, and told UK owners it was licensed here

   Four guides referred to an oral diabetes drug for cats called "Bexatil", and one stated plainly that bexagliflozin is "Bexatil in the UK, Bexacat in the US". There is no product called Bexatil. The drug is Bexacat, it is made by Elanco, and every source we can find for it is American — the FDA approval, the US label, the manufacturer's own pages. We could find no UK or European authorisation for it at all. The UK-licensed oral option for cats is Senvelgo (velagliflozin), which we had right. So we invented a brand name, attached it to a real drug, and told owners in this country that it was available to them. One of the guides was titled after it. The name is now gone from every page; the one guide that still mentions bexagliflozin says clearly that it is a US product and that your vet is the person to ask what can actually be prescribed here. This is the most serious error this page has carried. It was found during a pass that checked every clinical claim against a source we could open — not by anyone reading the prose, because it read perfectly plausibly.

6. 25 October 2026

   We overstated how far back a fructosamine test looks

   Two guides said a fructosamine test reflects average glucose over the previous two to three weeks. The ISFM consensus guidelines put it at roughly the preceding week, and the 2025 iCatCare consensus at seven to ten days. Nothing we could find supports two to three weeks. It matters because the test is what distinguishes real diabetes from a stress spike at the clinic, and an owner who thinks it looks back three weeks will read more into a borderline result than it can carry. Both pages now say a week to ten days.

7. 25 October 2026

   A page claimed a vet had reviewed it when no vet had

   The guide to oral treatment for diabetic cats attributed one of its contraindications to "a veterinary surgeon in clinical practice who reviewed this page in October 2026". That page was not among the thirteen Dr Simon reviewed. The sentence had been carried over from a sibling guide that she did review, and nobody noticed that the attribution travelled with it. The claim itself was correct and is on the product labelling, so the fact stands; the borrowed credit does not. The page now cites the labelling and links to the reviewed guide instead. We keep the list of reviewed guides in one file precisely so this cannot happen, and this is the case that got past it — because the claim was in the prose rather than in the byline.

8. 25 October 2026

   We corrected the free-feeding advice on one page and left the opposite advice standing on another

   On 24 October the cat feeding guide was corrected: the distinction that matters is measured versus unlimited, not bowl versus no bowl, and current feline guidance accommodates cats that graze on a weighed daily ration. The home monitoring guide was not changed with it, and went on saying "if your pet grazes all day, the insulin-food mismatch destabilises glucose. Scheduled meals are crucial." So an owner reading both pages was told their grazing cat could be managed by weighing intake, and that grazing destabilises diabetes. An external reviewer found it; we had not thought to check whether the correction had propagated. Both pages now say the same thing, and a correction is no longer treated as finished until the whole corpus has been searched for the old wording.

9. 25 October 2026

   Our own pages gave two different answers about whether the app interprets a glucose reading

   The homepage said Mello shows a reading and says nothing about it unless you have saved the range your vet set. The app page said Mello falls back to the ranges the profession works to and labels them as such. The homepage was right: a verdict against a number no vet gave for your animal was deliberately removed from the app in October, because that is the one thing the product promises not to do. The app page wording was ours, written the same week while correcting something else on that page. Both now render from a single statement, so the two cannot drift apart again. We are recording it because a contradiction about what a medical-adjacent product does is a more serious failure than a wrong fact in a guide.

10. 25 October 2026

    Our cat-food carbohydrate sum skipped a step, making wet food look far lower in carbohydrate than it is

    The feeding guide told owners to work out carbohydrate as 100 minus protein, fat, ash, fibre and moisture, and then compare the answer against a 5–10% target. Those are two different measures. The subtraction gives carbohydrate as fed; the target is on a dry matter basis, which is the food with the water taken out. For dry food the gap is small. For wet food it is enormous: a food at 3% as fed with 78% moisture is 13.6% on a dry matter basis — above target, and halfway to the consensus ceiling — while an owner following our page would have read 3% and thought it excellent. The page now gives both steps, a worked wet-food example, and the conversion in the FAQ answer that search engines quote. The error was pointed out by an external reviewer, not by us.

11. 25 October 2026

    We called free-feeding dangerous, which was too blunt to be true

    The cat feeding guide said leaving food out all day "is dangerous for a diabetic cat". The thing that matters is whether the amount eaten is known and measured, not whether it arrives in sittings — and current feline guidance accommodates cats that graze, using a weighed daily ration. Some cats will not eat to a schedule, and telling their owners they are doing something dangerous helps nobody. The page now draws the distinction between a measured ration and unlimited food, and says to tell your vet if your cat will not eat to a timetable so the insulin can be timed around how the cat actually eats.

12. 24 October 2026

    The glucose curves guide gave an "ideal shape" that does not exist

    The same vet then reviewed thirteen pages of this website. The curves guide told owners to expect a nadir 4–6 hours after injection and a return to baseline by 10–12 hours, presented as the ideal shape of a curve. Our own home monitoring guide said the opposite — "There is no single timetable that is true for every diabetic dog and cat" — and the reviewer confirmed the monitoring guide was right: every patient varies, and a curve is heavily influenced by stress and other factors on the day. The target timings are gone. The page now says plainly that there is no single ideal shape and gives no expected nadir, because an owner measuring their pet against a timetable that does not apply to it is the harm here.

13. 24 October 2026

    We said remission was possible for diabetic dogs

    The life expectancy guide said canine remission was "possible with aggressive weight loss and diet change", which contradicted our own remission guide saying dogs almost always need insulin for life. The reviewer was blunt: they do not remember ever seeing a diabetic dog go into remission in thirteen years of practice. The claim is withdrawn. The page now says remission in dogs is very rare and to plan for insulin for life. Holding out remission as an achievable goal to the owner of a newly diagnosed dog sets them up for a failure that was never available.

14. 24 October 2026

    One page gave two different carbohydrate targets for diabetic cats

    The feeding guide carried its own target of "under 10% carbs on a dry-matter basis" and, further down the same page, the 2025 iCatCare consensus figure of "below 25% on a dry matter basis". An owner reading it could not tell which to use. The reviewer resolved it: 25% is an upper limit, not a target, and the aim should be considerably lower — 5–10% in their experience. A food sitting just under 25% clears the guideline without being the diet you are aiming for, and the page now says so.

15. 24 October 2026

    Our hypoglycaemia first aid left out the first thing a vet would do, and read as a treatment rather than a bridge

    The page told owners to rub honey or glucose syrup on the gums. The reviewer added the step that comes before it — if the pet is awake and can eat easily, offer them a meal — and corrected the framing: honey is a bridge applied while you arrange transport, not something to carry on administering at home. It also gave no quantity at all, so an owner had no idea whether to use a smear or a jar; it now gives the reviewer's rough guide of a quarter to half a teaspoon for a small dog or cat, up to a tablespoon for a large pet. Separately, the guide for a pet that will not stabilise omitted U40 versus U100 syringe mismatch and the Somogyi effect, the two causes where an owner's instinct to give more insulin is the wrong one, and the injection guide did not say needles are single-use or mention sharps disposal. All are now covered.

16. 24 October 2026

    A vet reviewed the app, and the target ranges we fall back on were too tight

    We paid a practising RCVS-registered vet to review the app and tell us what was wrong with it. The ranges Mello uses where an owner has not entered one from their own vet were 5.0–12.0 mmol/L for dogs and 5.0–10.0 for cats, which the reviewer said were "ideal ranges, but they are tight" against current goals of 5–15 and 5–17. That matters because those figures are what every percentage and chart is measured against when no vet has set a range, so a band narrower than the profession's own goal made an ordinarily managed animal look worse than it is. They are now 5.0–15.0 and 5.0–17.0. The ceiling on a range an owner may enter came down from 30.0 to 20.0 in the same review.

17. 24 October 2026

    Ketones were recorded as a bare number, in an app for the one illness where they matter most

    A ketone reading had no threshold, no status and no alert: an owner could type any value and the app said nothing. The same review was unambiguous that a detection "should trigger a 'contact emergency vet now' warning", and it now does. The reviewer also pointed out that most glucose meters do not measure ketones at all, so the numeric field assumed equipment most owners do not have — an owner reading a urine dipstick either skipped the section or invented a number from a colour. A dipstick result can now be recorded as what it is.

18. 24 October 2026

    Nothing asked whether a pet had eaten before an injection was recorded

    Asked what owners managing a diabetic pet are never prompted about, the reviewer raised this unprompted as their biggest concern: insulin given to an animal that has not eaten or has been vomiting. Mello did warn when a refused meal was logged, but an owner opening the app only to record an injection never passed that warning. The app now asks before the dose is saved, and says to call the vet before injecting if the answer is no or uncertain. This reverses a decision we made on 14 October, when a sentence of that shape was removed from the app for telling owners what to do about a dose. The difference is whose instruction it is.

19. 15 October 2026

    Dose instructions removed from the FAQ and three guides

    Several pages told owners not to give a second dose, and the injection guide told them to "resume the normal schedule and check with your vet if unsure". Whether to skip, delay or give the next injection is a decision for a vet about one animal, and the guide made the vet optional. These pages now record what happened and route to the vet, and the general advice is attributed as what vets advise rather than stated as a rule to apply at home.

20. 15 October 2026

    A glucose range we had invented was removed from the curve diagram

    The diagram asked whether the nadir was "in a safe zone (typically 4.0–8.0 mmol/L)". That range is not one Mello holds, not one any source here supports, and calling any range "safe" is a judgement we are not in a position to make. Its shaded target band was also the default for a dog, shown without saying so on a page read by cat owners. Both are now labelled as one illustrative dog's vet-set range, and the checklist asks the reader to compare their curve with the range their own vet set.

21. 15 October 2026

    Claims about the app that the app did not do

    The report mockup showed a "glucose curve report" with a nadir and promised "full curve data"; Mello has no curve feature. The home-screen mockup showed a time-in-range dial and a days-logged counter that do not exist. Pages claimed activity logging, supply tracking, one-tap reports and reminders that mean "nothing depends on memory". A "Dry Matter Carbohydrate Calculator tool" was referenced five times and had never been built. Each has been corrected to what the app actually does, or removed.

22. 15 October 2026

    Every corrected guide was showing the wrong date

    Forty-six guides were corrected on 14 October, including safety content, and every one of them went on displaying "Last updated: 8 August 2026" while telling search engines it had been modified in October. Each guide carries two date fields and only one had been restamped. The visible date, the structured data and the site index now agree on every page, and the build checks all three.

23. 15 October 2026

    Authorship in our structured data

    Six pages and every guide published machine-readable data naming "Mello Editorial Team" as a person. There is no such person: Mello is one person, named on the about page. Collective names are now published as an organisation.

24. 15 October 2026

    What happens to a shared carer if a subscription lapses

    The terms and the privacy policy said an invited carer would keep "a read-only view of the last insulin entry" and that full shared care would stop. The app does no such thing: nothing is taken away from somebody already invited. Both documents now describe what actually happens.

25. 14 October 2026

    A partial-dose helper and a cost estimator were withdrawn

    An independent review found that the partial-meal dose helper strayed too close to a dosing decision, which is a line Mello does not cross. It was taken down rather than reworded. A monthly cost estimator went at the same time, for presenting an estimate with more confidence than its inputs deserved.

26. 14 October 2026

    Glucose thresholds removed from the homepage chart

    An example chart on the homepage labelled a "Target Zone (Dogs) 5.0–12.0" and a "Below Caution < 4.0". Published as a label on our own chart, those read as Mello's recommendation. Mello has no target range of its own and asks the owner's vet for theirs.

27. 14 October 2026

    The free tier stopped being capped at 30 days of history

    The pricing page promised "you are never locked out of your pet's records" and the free tier was capped at the last thirty days, four lines below. The cap is gone. Premium charges for what Mello makes, not for access to what you wrote down.
