Cat Insurance in Australia: Waiting Periods, Pre-existing Conditions and Exclusions Explained

The monthly price is the first thing most people look at when they buy cat insurance. But the price only tells you what you'll pay. Whether the policy actually pays you back depends on the fine print: waiting periods, pre-existing conditions, limits, excesses and exclusions.

These terms are where most disappointments happen. A claim for an illness that started in the first few weeks, a condition the vet noted a year ago, or a treatment with a small sub-limit can all leave you paying most of the bill yourself.

This guide explains each of these terms in plain English, with examples, so you can compare policies properly and avoid surprises when you need to claim. If you're still deciding whether to insure at all, start with our guide: Is cat insurance worth it in Australia?

This guide is general information, not financial advice. The exact terms of any policy are set out in its Product Disclosure Statement (PDS).

Waiting periods

A waiting period is the time after your policy starts during which you can't claim for certain things. Insurers use them so people can't buy insurance only after a pet becomes sick.

Typical waiting periods

Waiting periods vary between insurers and policies. Comparison sites report ranges like these:

These are examples, not rules. Moneysmart notes that waiting periods vary by type of treatment, so always check the PDS for each one.

What happens if your cat gets sick during the waiting period?

This is one of the most common reasons claims are refused. If your cat shows signs of an illness during the waiting period, that illness is usually treated as a pre-existing condition. That means it may never be covered under that policy, not just during the waiting period.

Moneysmart lists illnesses during the waiting period among common exclusions.

Can waiting periods be waived?

Sometimes. Canstar, citing the RSPCA, reports that some insurers are willing to waive certain illness waiting periods, for example when a pet is switching from another insurer or has had a recent vet check. Don't assume it; ask, and get it in writing.

Practical tips

• Buy cover before you need it, ideally when your cat is a young, healthy kitten.
• Book a vet health check shortly before the policy starts, so there's a clear record that your cat was healthy.
• Don't let a policy lapse. Starting a new one usually means new waiting periods.

Pre-existing conditions

A pre-existing condition is generally any illness, injury or condition your cat had, or showed signs of, before your cover started, or during the waiting period.

Compare the Market notes that this can include symptoms that were never formally diagnosed, such as limping, vomiting or a persistent cough noted in vet records.

Curable versus chronic conditions

Insurers often treat these two types differently.

Curable conditions are problems that can fully resolve, such as an ear infection, a skin rash or a urinary tract infection. Some insurers may reassess these for cover if your cat has been symptom-free for a set period. Compare the Market reports this is typically 12 to 18 months, at the insurer's discretion. CHOICE also mentions that some pre-existing conditions can be covered after 18 months without signs or symptoms.

Chronic or hereditary conditions need ongoing management, such as diabetes, arthritis, kidney disease or heart disease. These are often excluded permanently.

How insurers find out

Insurers can ask for your cat's full vet history when you apply or make a claim. If a condition is recorded in the vet notes before the policy began, it's likely to be classed as pre-existing. Be honest when you apply: failing to disclose a known condition can lead to claims being refused.

Why switching insurers can be costly

Moneysmart warns that anything previously claimed for would be considered a pre-existing condition by a new insurer. CHOICE calls this a "loyalty penalty".

For example, if your cat was treated for a bladder problem under your current policy and you switch to a cheaper one, the new insurer may exclude bladder problems. If the problem comes back, you'd pay for it yourself.

Before you switch, list every condition your cat has been treated for and ask the new insurer, in writing, how each would be treated.

Benefit limits and sub-limits

Annual benefit limit

This is the most the policy will pay in a policy year across all claims. Once you reach it, you pay the rest until the policy renews.

Sub-limits

Many policies also cap how much they'll pay for particular conditions or treatments, even if you haven't reached the annual limit.

CHOICE gives the example of a policy with a $12,000 annual limit but a $1,000 sub-limit for tick paralysis. Moneysmart gives the example of a $2,000 procedure covered only up to $500.

For context, PetSure claims data from 2025, reported by Finder, showed an average treatment cost of $3,484 for tick paralysis in dogs. A $1,000 sub-limit wouldn't go far. If you live on the east coast, check sub-limits for paralysis ticks and snake bites carefully.

Common areas where sub-limits appear include:

• Tick paralysis
• Dental treatment
• Specific surgeries
• Consultation fees (CHOICE notes most policies cap these at around $300)
• Emergency or after-hours fees
• Alternative therapies

Benefit percentage and excess

These two settings control how much of each bill you get back.

Benefit percentage

Most policies pay a percentage of eligible costs, such as 70%, 80% or 90%. CHOICE notes that some policies that pay 100% for young pets reduce this to as low as 65% as pets get older.

Excess

The excess is an amount you pay before the insurer pays anything. Some policies apply it per claim, others per condition, per year or per accident. A higher excess usually means a lower premium.

Worked example

Imagine a vet bill of $4,000 for an eligible illness, with a policy that pays 80% and has a $200 excess per condition.

Insurers calculate this in different orders, and sub-limits can reduce the payment further, so ask for a worked example using the actual policy terms.

Common exclusions

Exclusions are things a policy won't pay for. Moneysmart and Compare the Market list these as common.

Routine and preventive care

Vaccinations, flea, tick and worm treatments, desexing, routine dental checks and microchipping are generally not covered by accident or illness policies. Some comprehensive policies or wellness add-ons contribute to these costs.

Elective and cosmetic procedures

Treatments that aren't medically necessary are usually excluded. Moneysmart lists elective treatments such as desexing.

Bilateral conditions

Moneysmart lists bilateral conditions as a common exclusion. These are conditions affecting both of a pair of body parts, such as both eyes, ears or knees. If your cat has a problem in one eye that's then excluded, some policies will also exclude the same problem in the other eye.

Diseases that can be prevented by vaccination

Moneysmart lists diseases with a known vaccine as a common exclusion. Keeping your cat's vaccinations up to date protects your cat and keeps your cover intact.

Dental disease

Compare the Market notes that many policies exclude dental disease, or cover it only if your cat has documented regular dental checks.

Pregnancy and breeding

Most policies exclude pregnancy, birth and breeding complications.

Less common exclusions

Moneysmart notes that some policies exclude skin conditions or tick bites. These are worth checking if you live in a paralysis tick area.

Renewals: what can change

Pet insurance is usually renewed every year. CHOICE warns that at renewal, insurers can change:

• Your premium (often rising with age, and sometimes after claims)
• The benefit percentage
• Limits and sub-limits
• Exclusions

Read every renewal notice carefully and compare it with last year's.

Checklist before you buy

Use this list when comparing policies:

• [ ] What are the waiting periods for accidents, illness and orthopaedic conditions?
• [ ] How does the policy define a pre-existing condition?
• [ ] Can curable conditions be covered again after a symptom-free period? How long?
• [ ] What is the annual benefit limit?
• [ ] What sub-limits apply, especially for tick paralysis, snake bite and dental?
• [ ] What percentage of eligible costs is paid, and does it change with age?
• [ ] What is the excess, and is it per claim, per condition or per year?
• [ ] What are the main exclusions?
• [ ] Is there a maximum entry age?
• [ ] How do claims work, and how long do they take to pay?

A real-world example: how the fine print plays out

Imagine two owners insure similar young cats on the same day.

Owner A notices their cat vomiting a few times in the second week of the policy and takes it to the vet. The vet records the vomiting. Months later, the cat is diagnosed with a gut condition. Because the first signs appeared during the illness waiting period, the insurer may treat the condition as pre-existing and decline the claim.

Owner B booked a vet check the week before the policy started, and the vet recorded a healthy cat. Their cat is later diagnosed with the same condition, with no earlier signs in the records. The claim is assessed under the normal policy terms, and paid according to the benefit percentage, excess and any limits.

The two cats had the same illness. The difference was timing and records. This is why insuring early, getting a pre-policy vet check and keeping good records matter so much.

Questions to ask the insurer before you sign

Phone or email the insurer and ask these questions directly. Keep their written answers with your policy documents.

1. "If my cat shows signs of an illness during the waiting period, will that condition be excluded permanently?"
2. "Which of my cat's past vet visits would you treat as pre-existing?"
3. "What sub-limits apply to tick paralysis, snake bite, dental disease and emergency fees?"
4. "Does the benefit percentage or excess change as my cat gets older?"
5. "Can I claim at the vet, or do I need to pay first and claim later?"

Clear answers in writing make it much easier to resolve any dispute later.

How to avoid a rejected claim

1. Insure early, before any health problems are recorded.
2. Get a vet check just before cover starts.
3. Disclose everything you know about your cat's health when applying.
4. Keep vaccinations and vet checks up to date, since some exclusions depend on them.
5. Keep records: invoices, vet notes and policy documents.
6. Check cover before non-urgent treatment. Many insurers will tell you in advance whether a planned treatment is covered.
7. Don't let your policy lapse, and think carefully before switching.

If your claim is refused

If you disagree with a decision:

1. Ask the insurer, in writing, for the specific reason and the policy clause relied on.
2. Use the insurer's internal complaints process.
3. If that doesn't resolve it, contact the Australian Financial Complaints Authority (AFCA), which Moneysmart notes offers free, independent dispute resolution.

Frequently asked questions

Is a waiting period the same as a pre-existing condition?

No, but they're linked. The waiting period is a set time after cover starts when you can't claim for some things. Any illness that starts during that time is often treated as pre-existing, so it may be excluded permanently.

Will my cat's old ear infection be excluded forever?

Not necessarily. Some insurers treat curable conditions, such as an ear infection, as eligible again after a symptom-free period, often 12 to 18 months. Others don't. Ask the insurer and check the PDS.

Does cat insurance cover desexing?

Usually not. Desexing is elective and commonly excluded, though some comprehensive policies or add-ons contribute to it.

Why did my premium go up?

Premiums usually rise as cats get older. CHOICE has also reported premiums rising after claims. Insurers can change premiums at each renewal.

What is a bilateral condition?

A condition that can affect both of a pair of body parts, such as eyes, ears or knees. Some policies exclude the second side if the first was already affected.
