Health conditions British Shorthairs are prone to

British Shorthairs are Australia's third most popular insured cat, and the PetSure figures separate them clearly from the average. Eye infections run at 5.2% and ear infections at 3.4%, both more than double the typical feline rate. Gastroenteritis sits at 7.8% and skin conditions at 3.7%, each above average. PetSure attributes the eye and ear pattern to the breed's facial structure and genetics. Alongside that sit two inherited conditions that do not show in claim frequency but dominate claim value.

Polycystic kidney disease (PKD)$1,500 to $4,000 per year once establishedInherited, DNA test available, screened by reputable breeders
Hypertrophic cardiomyopathy (HCM)$2,000 to $6,000, more over a lifetimePetSure notes higher heart condition risk in the breed
Eye infections and conditions$400 to $1,500 per episodePetSure records 5.2%, more than twice the feline average
Ear infections$300 to $900 per episodePetSure records 3.4%, more than twice the feline average
Gastroenteritis$500 to $2,500 per episodePetSure records 7.8%, well above the feline average
Skin conditions$600 to $2,000 per yearPetSure records 3.7%, above the feline average
Dental disease$800 to $2,000 per procedureRarely covered without a dental add-on
Worth noting: Eye and ear conditions at twice the feline rate are the claims most likely to recur. Insurers differ in whether each flare-up counts as a new claim or a continuation of one, and where it is treated as a continuation, a per-condition cap applies across the animal's life rather than resetting each year.

What insurance costs for a British Shorthair

Compare the Market's quote analysis puts the Australian cat average at around $619 a year, roughly $52 a month, against $1,192 for dogs. British Shorthairs claim above the feline average in four of the categories PetSure measures, so expect quotes towards the upper end of the cat range. No Australian source publishes premiums by cat breed.

Indicative monthly premiums, comprehensive accident and illness cover
AgeTypical monthly premium
Kitten, under 1 year$35 to $55
2 to 4 years$50 to $80
5 to 8 years$80 to $125
9 years and over$125 to $200

Policy terms that affect claims for this breed

Three parts of a PDS have more bearing on what a British Shorthair claim pays than the headline premium does. What follows describes how those terms operate. It is not a recommendation to buy or hold any particular policy.

1. How sub-limits on recurring and hereditary conditions work

Two structures matter here. A per-condition cap interacts badly with recurring eye and ear problems, because the same condition returns rather than resolving. And a cardiac or renal sub-limit constrains the two inherited conditions that produce the largest lifetime claims. Policies with no sub-limits are bounded only by the annual limit.

2. How waiting periods apply

The standard 30 day illness waiting period applies. Because eye and ear problems appear early and often in this breed, anything noted in the clinical history before cover starts is treated as pre-existing. Kidney and heart findings from a routine examination have the same effect on those categories.

3. How exclusions are defined

Ask how the insurer treats recurring conditions, since the breed's most frequent claims recur. Also check whether polycystic kidney disease and hypertrophic cardiomyopathy fall inside a hereditary exclusion, because both are inherited and both are screened for in reputable breeding lines.

Common questions

What health problems do British Shorthairs have?
PetSure's Australian claim data records eye infections at 5.2% and ear infections at 3.4%, both more than double the feline average, plus gastroenteritis at 7.8% and skin conditions at 3.7%. Separately, the breed carries inherited risk of polycystic kidney disease and hypertrophic cardiomyopathy.
Is polycystic kidney disease covered by pet insurance?
Where it develops after cover starts and the policy does not exclude hereditary conditions, it is generally covered as an illness. Because it is managed over years rather than cured, the practical constraint is usually the annual limit or a renal sub-limit rather than coverage itself.
Are British Shorthairs expensive to insure?
Above the feline average, on the basis that they claim above average in four of the categories PetSure measures. Australian cat cover averages around $619 a year overall, and no source publishes premiums by cat breed, so the figures on this page are indicative.
Do British Shorthairs need eye checks?
Eye conditions occur at more than twice the feline rate in this breed, so they present frequently. Anything recorded before a policy starts becomes pre-existing, which is why the timing of cover relative to the first examination matters.

Summary

British Shorthairs are among the clearest cases in PetSure's cat data for reading the claim categories rather than the headline. Eye and ear conditions at more than twice the feline rate are frequent and recurring, and polycystic kidney disease and hypertrophic cardiomyopathy are inherited and managed across years. Both patterns are the kind constrained by per-condition caps rather than by the annual limit.
