Cats are living longer than ever, with indoor cats regularly reaching 18-20 years. But with longer lives come more health issues, making insurance for older cats both more important and more complicated. Here is what you need to know about insuring a senior cat in the UK.
When Is a Cat Considered Senior?
Most insurers classify cats as senior at age 10-12, somewhat later than dogs. This reflects the fact that cats generally have fewer health issues in middle age compared to dogs. However, once cats do develop age-related conditions, they can be just as expensive to treat — chronic kidney disease, hyperthyroidism, and diabetes are all common in older cats and require ongoing management.
Common Health Issues in Older Cats
Understanding the conditions your cat is likely to face helps you assess whether insurance is worthwhile. Chronic kidney disease is the most common serious condition, affecting up to 30% of cats over 15. Treatment involves regular blood tests, prescription diet, fluid therapy, and medication — costs that can reach £200-400 per month. Hyperthyroidism affects approximately 10% of cats over 10 and requires daily medication or radioactive iodine treatment (£2,000-3,000). Diabetes requires twice-daily insulin injections and regular monitoring, costing £100-200 per month.
Premium Increases and Co-Payments
Like dogs, cat insurance premiums rise with age. However, because cats tend to develop expensive conditions later in life, the premium curve is slightly different — increases may be less steep in middle age but accelerate sharply after 12-14. Most policies introduce a 20% co-payment at age 10-12 for cats. This means if your cat has a £1,000 vet bill with a £100 excess, you would pay £100 + 20% of £900 = £280, with the insurer paying £720.
Insuring an Older Cat for the First Time
Fewer providers impose strict upper age limits for cats compared to dogs, so you may find it easier to get a new policy. However, the same pre-existing condition rules apply. If your cat has any veterinary history of kidney issues, thyroid problems, or other conditions, these will likely be excluded.
Some providers offer "senior cat" policies specifically designed for cats over 8-10. These may have lower vet fee limits but can still provide meaningful protection against unexpected emergencies and new conditions.
Indoor vs Outdoor Cats
Some insurers offer lower premiums for indoor-only cats, recognising that they are less likely to be injured in road accidents or cat fights. If your older cat has transitioned to an indoor lifestyle, make sure your insurer knows — you could be paying more than you need to. However, indoor cats are still susceptible to all the same illnesses, so the saving is typically modest.
Our Advice for Senior Cat Owners
If your cat is already insured, keep the policy going. The cost of treating chronic kidney disease or diabetes alone can dwarf years of premiums. If your cat is not insured, get cover as soon as possible — every year you wait increases the chance of a condition developing that will be excluded. Compare providers specifically on their senior cat terms, including co-payment thresholds, vet fee limits, and whether they cover ongoing prescription medication.
