When shopping for pet insurance for cats, you may come across the term underwriting. While it’s often buried in the fine print, underwriting plays a critical role in determining your cat’s eligibility, premium, and coverage limits. In fact, it’s the invisible process that determines whether your cat will be approved for coverage, and what that coverage will cost.

For cat owners who want to make informed decisions—not just buy the cheapest policy—understanding how underwriting works is essential. In this guide, we break down the concept of underwriting, how it affects your cat insurance policy, and what to expect when your application is reviewed.

What Is Underwriting in Cat Insurance?

In simple terms, underwriting is the risk evaluation process an insurance company uses to decide:

  • If your cat qualifies for coverage
  • What your monthly premium should be
  • Whether specific conditions will be excluded

This process can be manual or automated and may take place before your policy is issued (pre-underwriting) or after you file your first claim (post-underwriting).

Pre-Underwriting vs. Post-Underwriting

1. Pre-Underwriting (Proactive Review)

With this model, the insurer reviews your cat’s medical history up front—before issuing the policy. They assess:

  • Vet records
  • Past diagnoses or symptoms
  • Any known pre-existing conditions

This allows the insurer to clearly define exclusions from the start, so you know exactly what’s covered.

2. Post-Underwriting (Reactive Review)

Some insurers skip in-depth review until a claim is filed. At that point, they’ll request your cat’s medical history to determine if the issue was pre-existing.

This model offers faster enrollment but may lead to surprise denials later if past symptoms are uncovered.

What Factors Influence Underwriting Decisions?

Just like human health insurance, underwriting for cats involves multiple factors. Here’s what insurers typically look at:

1. Age

The older your cat, the higher the risk—and therefore the premium. Some insurers won’t accept new applications for senior cats over 14, while others may offer limited coverage or higher deductibles.

2. Breed

Certain cat breeds are more prone to hereditary conditions. For example:

  • Maine Coons – heart disease
  • Persians – kidney disease and respiratory issues
  • Sphynx – skin disorders

Underwriters account for these risks when determining premium costs or policy exclusions.

3. Pre-Existing Conditions

Any condition your cat showed symptoms of before enrollment may be flagged. Common examples include:

  • Recurring urinary tract infections (UTIs)
  • Chronic diarrhea or vomiting
  • Arthritis or mobility issues

Underwriting will determine whether these conditions are permanently excluded or eligible for limited coverage.

4. Lifestyle Factors

Some insurers ask whether your cat is indoor-only or allowed outdoors. Outdoor cats may be considered higher risk due to potential exposure to fights, poisons, or injuries.

How Underwriting Affects Your Premium

Underwriting doesn’t just decide if you get coverage—it shapes your monthly premium. The riskier your cat is to insure, the more you’ll pay. This is why quotes can vary widely even for the same age or breed depending on:

  • Your cat’s health history
  • Your location
  • The insurer’s underwriting standards

Two identical cats in different ZIP codes could receive very different quotes based on local vet costs and risk data.

Underwriting and Claim Denials

Many cat insurance claim denials are traced back to underwriting. If a claim is denied because the insurer determines the condition was pre-existing, it’s typically due to how the underwriting process interpreted prior symptoms or treatments.

That’s why it’s crucial to be honest and thorough when applying. Misrepresenting information—even unintentionally—could result in denied claims or policy cancellation.

How to Navigate the Underwriting Process

1. Request a Medical Review Up Front

Some insurers offer voluntary pre-policy medical reviews. This gives you clarity on what will or won’t be covered—and eliminates surprises at claim time.

2. Keep Good Vet Records

Accurate and complete veterinary documentation helps the underwriting team assess your cat’s history quickly and fairly.

3. Ask Specific Questions Before Enrolling

If your cat has had any prior conditions, ask the insurer how those will be treated under underwriting. Will they be permanently excluded? Will there be a waiting period?

4. Consider Early Enrollment

The earlier you insure your cat, the fewer medical issues will exist for underwriters to flag. Kittens, in particular, get the most favorable underwriting outcomes and lowest premiums.

Real-Life Example: How Underwriting Impacts Claims

Let’s say your cat had vomiting episodes six months before you enrolled. You didn’t think it was serious and never got a formal diagnosis. Months later, your cat is diagnosed with inflammatory bowel disease (IBD). The insurer pulls vet records and sees the earlier vomiting noted in progress notes. They may rule this a pre-existing condition—even if you never filed a claim until now.

This is why proactive underwriting—done before a claim—is usually in your best interest, even if it takes longer to enroll.

Can Underwriting Be Appealed?

Yes, in some cases. If you disagree with how a claim was handled or how a condition was classified as pre-existing, you can request a review or appeal. Having strong documentation from your vet stating that the condition is new and unrelated can help your case.

Underwriting Is the Gatekeeper of Cat Insurance

While it may seem like a behind-the-scenes process, underwriting directly impacts your policy eligibility, premium cost, and claim outcomes. Understanding how it works empowers you to make smarter decisions, ask the right questions, and protect your cat with confidence.

Whether you’re insuring a new kitten or an aging rescue, clear communication with your insurer—and an honest review of your cat’s health history—can help you avoid surprises and ensure your pet insurance for cats works as expected when you need it most.
