Chronic conditions

Chronic conditions in cats, tracked properly

A cat with a long-term condition needs a record a vet can read. FelineSense keeps one for the three that matter most in cats: diabetes, chronic kidney disease and an overactive thyroid.

Diabetes

Feline diabetes, managed without the shoebox of notes

Insulin or a once-daily oral medicine, glucose, curves and expiry dates: the whole job, in one screen.

Insulin or an oral medicine, exactly as prescribed

For cats on insulin injections or a once-daily oral medicine. You copy the dose your vet wrote; the app never calculates, suggests or adjusts a dose. Each dose is logged with a “did the cat eat?” check first, and your vet’s standing instruction for a cat that will not eat is kept with the plan.

Options for given, gave reduced and skipped, so the record matches what really happened, and injection sites that rotate through the sides, flanks and hips.

Glucose log with a verdict

Readings in your meter’s units, mg/dL or mmol/L, set once. Every reading comes back with a plain verdict against the feline target, 80–300 mg/dL through the day. One high reading is common, because stress raises glucose in cats; a run of readings over 300 is a call to the vet.

Use a pet meter set to the cat code: human meters read low in cats.

The day curve, and the nadir

Plot a day of readings into a curve and the app marks the nadir, the lowest point and when it fell (ideally 80–150 mg/dL), with the peak and the average. That is the number a vet needs to judge the dose, and the hardest thing to produce from scribbled notes.

Cats can go into remission. A reading under 80 is flagged for the vet today, because in a cat it can mean the dose is now too high or that remission is starting. The vet decides; you never lower a dose yourself.

Opened-vial expiry

Insulin weakens once opened. You enter the date you opened the vial or pen and the number of days its label allows; the app counts down, so you are not quietly injecting weak insulin and wondering why the numbers drifted.

The emergency signs, one tap away, not in a drawer

Low blood sugar and ketoacidosis are the two emergencies in a diabetic cat, and they tend to happen when nobody is thinking clearly. Both lists sit on the diabetes screen, one tap to open: weak or wobbly, shaking, glassy-eyed, collapse or seizure for low sugar; vomiting, not eating, deep lethargy, sweet breath or fast breathing for ketoacidosis.

A reading under 60 mg/dL is treated as an emergency: food if the cat can eat; if it is too weak to eat, a little corn syrup or honey rubbed on the gums (never poured into the mouth); no insulin; and a call to the vet now. On the oral medicines, ketoacidosis can happen with a normal glucose, so for a cat on one the app keeps that warning on the diabetes screen and in each reading’s verdict.

Kidney disease

Chronic kidney disease in cats, in the vet’s own bands

One of the most common illnesses of older cats. Keep the stage, diet and fluids together, and watch weight, appetite, vomiting and water.

The vet’s plan, in one place

The IRIS stage exactly as your vet told you, the renal diet, the phosphate binder and the sub-Q fluids as prescribed, with a reminder on the prescribed interval and a given or skipped log. The app never stages the disease itself: staging needs a fasted, well-hydrated cat and repeat tests, and that is the vet’s call.

Every lab panel, against the IRIS bands

Enter creatinine, SDMA, phosphorus, systolic blood pressure and urine specific gravity from the lab sheet. Each value is shown in its IRIS band (creatinine under 1.6 mg/dL is band 1, 1.6–2.8 band 2, 2.9–5.0 band 3, over 5.0 band 4), and anything above the stage or phosphorus target your vet set is flagged to raise with them. Context, never a diagnosis.

The home signs that matter

Not eating: call the vet now, because a kidney cat that stops eating can go downhill fast. Losing 5 % or more of body weight within two months: call the vet, as weight loss is the earliest sign of progression. Vomiting, or drinking over 60 mL/kg a day: worth watching and telling the vet.

Hyperthyroidism

Hyperthyroidism in cats, followed result by result

Common in cats over 10: weight loss with a big appetite, restlessness, a racing heart.

The treatment your vet chose

Methimazole or carbimazole, radioiodine (I-131), an iodine-restricted prescription diet, thyroid surgery, or not decided yet. You enter the T4 reference range from your lab, because labs differ. Methimazole doses are logged under Medications, exactly as prescribed.

Each T4, against the goal

Every result is placed against the range: above it, in the upper half, in the lower half (the AAFP goal for a treated cat), or below it, which can mean over-treatment and can harm the kidneys. Creatinine is logged beside it, because treating the thyroid can unmask kidney disease. Rechecks every 3–6 months.

Home signs and an early side-effect watch

For 90 days after methimazole starts, vomiting, facial itching or lethargy is flagged as a possible side effect, with a prompt to call the vet that day. The app also watches for weight loss of 5 % or more within two months, a resting heart rate over 220 beats a minute, and a cat that stops eating.

What is next

More conditions, same discipline

Every condition follows the same discipline: the prescribed treatment logged faithfully, readings with a plain verdict, the numbers a vet actually uses, and the warning signs always within reach. The app never calculates a drug dose. That is how further conditions will be added.
