Home glucose monitoring: meters, sensors, and how to choose

The first time you take your pet's blood glucose at home, your hands will probably shake a little. A week or two later, it's part of the routine — and you'll be gathering information that genuinely improves your vet's decisions. Home monitoring is increasingly recommended in veterinary guidelines for a simple reason: it shows your pet's real life, not their stressed clinic visit.

Why home readings often beat the clinic's

Many pets — cats especially — get stressed at the vet, and stress pushes blood glucose up (vets call it stress hyperglycaemia). A reading taken at home, with your pet relaxed on their own sofa, often reflects their true glucose far better than one taken under clinic strip lights. That's why your calm home record can be worth more than an expensive, anxious afternoon at the practice.

Do I need a special pet glucometer?

This one matters: dog and cat blood distributes glucose differently from human blood, so human glucometers can read inaccurately for pets — often underestimating. A meter calibrated specifically for dogs and cats gives more reliable numbers, which is why most vets recommend one for home monitoring. If you already own a human meter, ask your vet how to interpret it rather than assuming the numbers transfer.

What about continuous glucose monitors?

Continuous glucose monitors — small sensors worn on the skin, streaming readings to a phone for up to a couple of weeks — are increasingly used in pets and can be transformative, especially for cats who hate being pricked. They make building a full glucose curve almost effortless and catch overnight lows you'd never see with spot checks. They're usually fitted with your vet's involvement.

What you'll need to start

For spot checks: a pet-calibrated glucometer, its test strips, and lancets for a small drop of blood — usually from the edge of the ear or a paw pad. Your vet or nurse will show you the technique, and it's a faster skill to pick up than you'd expect.

Whatever you measure with, Mello turns the readings into a clear curve and a vet-ready report — one tap.
