Diabetes Management

Ongoing insulin regulation, glucose monitoring, and diet planning so diabetic dogs and cats can live comfortably and stably — managed by internal medicine specialists right here in Calabasas.

Diabetes mellitus occurs when the body cannot produce enough insulin or cannot respond to it properly, leaving cells starved for glucose while blood sugar climbs to damaging levels. It is a manageable condition — thousands of dogs and cats live well for years after diagnosis — but it requires consistency, owner engagement, and a veterinary team experienced in navigating the adjustments every diabetic patient inevitably needs. Dr. Brian Norman is a Diplomate of the American College of Veterinary Internal Medicine (ACVIM), and internal medicine cases like diabetes are a focus of his practice. With in-house laboratory testing, the team can often adjust insulin doses and assess stability without requiring outside referrals.

How It Works

Successful diabetes management rests on three pillars: the right insulin, the right diet, and consistent monitoring. After diagnosis — confirmed with blood glucose and urine glucose measurements, and a fructosamine level to assess average control — the veterinarian establishes an initial insulin protocol and feeding schedule:

  • Insulin selection and dosing — dogs and cats often require different insulin types; cats frequently achieve remission (a return to insulin independence) with early, tight regulation, making the initial phase especially important
  • Dietary change — high-protein, low-carbohydrate diets are preferred for cats; consistent, timed meals tied to insulin injections are critical for both species
  • Glucose curves — a series of blood glucose measurements taken over 12 hours (in-hospital or increasingly via continuous glucose monitors) shows how the pet responds to each insulin dose and guides adjustments
  • Regular rechecks — fructosamine or hemoglobin A1c testing every 1–3 months tracks average long-term control; the dose is adjusted as the pet's needs change with weight, diet, activity, or concurrent illness

What to Expect

The first few weeks of diabetes management involve frequent communication and potentially several dose adjustments as the right insulin level for the individual pet is established. Owners learn to give injections confidently — a skill most find much easier than expected — and to recognize the signs of hypoglycemia (low blood sugar), which include weakness, wobbling, seizures, or collapse and require immediate attention. Over time, as the pet stabilizes, recheck intervals space out and daily management becomes routine. Some diabetic cats achieve remission within weeks to months of starting treatment; dogs generally require lifelong insulin. Concurrent conditions — such as urinary tract infections, pancreatitis, or obesity — can affect regulation and are addressed as they arise.

Good Candidates

  • Dogs and cats newly diagnosed with diabetes mellitus who need initial insulin selection, dose finding, and owner education
  • Diabetic pets whose current regulation is unstable — recurring high or low glucose readings, persistent weight loss, or ongoing lethargy
  • Cats whose diabetes may be in early-enough stages to attempt remission with intensive management and dietary change
  • Diabetic pets with concurrent conditions (urinary tract infections are common in diabetic dogs; hyperthyroidism commonly coexists in diabetic cats) that complicate regulation
  • Owners who are newly managing insulin injections at home and want guidance and support through the learning period

Frequently Asked Questions

1How do I manage my diabetic cat at home?
Managing a diabetic cat at home means giving insulin injections twice daily (with meals), feeding a consistent high-protein, low-carbohydrate diet, and watching for signs of hypoglycemia. Your veterinarian will walk you through the technique and create a monitoring schedule — most owners become very comfortable with the routine within a few weeks.
2Can a diabetic dog or cat be cured?
Some cats — particularly those diagnosed early and started on tight glucose control with a low-carbohydrate diet — achieve diabetic remission and no longer require insulin. Dogs rarely achieve remission and typically need lifelong treatment, though well-regulated dogs live normal, comfortable lives.
3What happens if I skip an insulin dose for my pet?
Missing an occasional dose is unlikely to cause immediate crisis — the blood sugar will rise but usually not to emergency levels — but consistent missed doses lead to poor regulation, weight loss, and increased risk of diabetic ketoacidosis (DKA), a serious complication. Contact the veterinary team for guidance if a dose is missed.
4What are the signs of low blood sugar (hypoglycemia) in a diabetic pet?
Watch for sudden weakness, stumbling, glassy eyes, trembling, seizures, or loss of consciousness. If any of these occur and insulin was recently given, rubbing corn syrup or glucose gel on the gums and seeking emergency care immediately is the right response.
5How often does a diabetic pet need to see the vet?
During the initial regulation phase, rechecks may occur every one to two weeks; once stable, most diabetic pets are seen every three months for a fructosamine or glucose curve. Any change in appetite, water intake, weight, or insulin response warrants an earlier visit.
6What is a glucose curve and why does my pet need one?
A glucose curve measures blood sugar at intervals over 12 hours to see how high it rises before insulin takes effect, how low it drops at peak action, and when it returns to baseline. This profile is far more informative than a single reading and is the standard tool for adjusting insulin doses safely.
7What causes diabetes in dogs and cats?
In dogs, diabetes most often results from insulin-secreting cell destruction (similar to type 1 in humans), often associated with pancreatitis or hormonal conditions like Cushing's disease or pregnancy. In cats, it is more similar to type 2 — obesity, high-carbohydrate diets, and chronic inflammation of the pancreas are common contributing factors.
8Will my diabetic pet always be thirsty and urinating a lot?
Excessive thirst and urination are classic signs of uncontrolled diabetes — as blood sugar drops into a better-regulated range with insulin and diet, these signs typically improve significantly. Persistent polyuria (excessive urination) after starting treatment suggests the current protocol needs adjustment.
