Diabetes mellitus is one of the most common chronic conditions in cats and dogs, and managing it involves ongoing costs: insulin, syringes, glucose monitoring (including continuous glucose monitors), regular vet visits, and bloodwork — often for the rest of your pet’s life. If your pet is already diabetic, finding new coverage is difficult since it would be excluded as pre-existing. But if your pet isn’t yet diagnosed, choosing the right plan now can make a significant difference later. This guide explains how to think about diabetes coverage, building on our beginner’s guide to pet insurance.
Quick Answer: What to Prioritize
| Priority | Why It Matters | What to Look For |
|---|---|---|
| Unlimited or high annual limit | Lifelong condition means costs accumulate every year, indefinitely | Healthy Paws, Trupanion, Pets Best, MetLife (unlimited option) |
| Chronic condition coverage continuity | Diabetes is covered for life once enrolled, as long as policy is maintained | Confirm provider doesn’t reduce coverage for chronic conditions over time |
| Percentage-based reimbursement | Insulin and monitoring costs recur monthly | 70–90% reimbursement on ongoing prescription costs |
| Enroll before diagnosis | Diabetes diagnosed before enrollment = pre-existing, excluded permanently | Enroll healthy pets as early as possible, especially predisposed breeds |
Approach Taken to Develop this Guide
The first step we took was to evaluate how providers deal with chronic diseases like diabetes: Does coverage include prescription medications? Monitoring equipment? Are the limits applied on an annual basis such that they allow for lifelong treatment of the condition? Also, does the policy address pre-existing conditions?
What it Really Costs to Manage a Diabetic Pet
Costs associated with managing a diabetic animal are often comprised of: insulin (costing anywhere between $40-$100+ per vial, requiring several vials per month), syringes, blood glucose testing curves performed by the veterinarian (costing $100-$300+ per session) as well as routine wellness visits aimed at identifying any complications, diabetic cataracts or ketoacidosis. These costs may easily add up to many thousands of dollars every year.
Why Unlimited Annual Coverage Matters Most Here
Unlike a one-time surgery, diabetes management is a recurring annual cost that compounds over your pet’s lifetime. A plan with a $5,000 annual limit might be more than enough in year one, but if your pet later develops a diabetes-related complication (like diabetic neuropathy or cataracts requiring surgery) in the same year as routine management costs, that limit can be reached faster than expected. See our unlimited coverage guide for providers offering no annual cap.
Reimbursement Math for a Diabetic Pet
With percentage-based reimbursement (the most common model — see our reimbursement explained guide), ongoing monthly insulin and supply costs are reimbursed at your selected rate after your deductible is met for the year. Because these are recurring monthly expenses, even a modest reimbursement percentage can add up to substantial savings over a year, compared to a benefit-schedule plan that might cap medication reimbursement at a fixed monthly amount regardless of actual cost.
Which Breeds Are at Higher Risk?
Certain breeds — including Australian Terriers, Samoyeds, Miniature Schnauzers, and some larger senior dogs, as well as Burmese cats — have elevated diabetes risk. If you own one of these breeds, enrolling while young and healthy (before any blood sugar irregularities are documented) is especially valuable. See our puppy insurance guide and kitten insurance guide for getting ahead of breed-specific risks.
What If My Pet Is Already Diabetic?
If your pet already has a diabetes diagnosis, new insurance generally won’t cover costs related to that diagnosis, as it would be classified as pre-existing by any new provider. In this situation, insurance may still be worth having for unrelated future conditions — see our is pet insurance worth it analysis for how to think about this tradeoff.
Frequently Asked Questions
Is insulin for my pet’s diabetes covered by pet insurance?
Yes, if the condition was diagnosed after you signed up for pet insurance and passed the waiting period, then continuing prescription drugs like insulin would be covered under medical care, according to your payout percentage and maximum.
What about continuous glucose monitors?
Continuous glucose monitors fall into the new technology category, and their coverage is subject to change.
Does diabetes ever go into “remission” for insurance purposes?
Some cats can achieve diabetic remission with early, aggressive treatment, but the diagnosis itself remains in your pet’s medical history — relevant if you ever switch insurers.
Is there a waiting period specifically for chronic conditions like diabetes?
Diabetes falls under standard illness coverage, so the regular illness waiting period (typically 14 days) applies — see our waiting periods guide.
