Senior Cat Insurance: Age Limits, Costs and What It Covers

When is a cat a senior, and can you still insure one?

The AVMA considers cats senior after age 10, and most insurers will still sell a policy at that age. The catch is what the policy can cover. By 10, many cats already have notes in their vet records, and those become exclusions.

Age shapes three things: whether you can enroll, what you pay, and how much of your cat’s health is already off the table. The sections below take each in turn. If you are new to the basics, our cat insurance guide explains how policies work for cats of any age.

What are the age limits for older cats?

Age limits for cats range from the 14th birthday to none at all. Here is what insurers state on their own pages or in major reviews.

Insurer	Upper age limit for new cats	Catch
Trupanion	Must enroll before the 14th birthday	Lifelong coverage once enrolled
Embrace	No upper age limit	Cats 15 and older can only get accident-only cover
Pets Best	No age limits	Premiums rise with age
ASPCA	No upper age limit for cats (per NerdWallet)	Confirm pricing on a quote

Not every insurer publishes its cutoff. Lemonade’s FAQ, for example, says a pet past its age limit “may be declined entirely” but does not name the age. If your cat is 12 or older, check eligibility before you fill out a long application.

The good news: age cutoffs apply to new enrollments. Once your cat is on a policy, most insurers let you keep renewing.

How much does senior cat insurance cost?

Senior cat insurance usually costs well above the young-cat price, and it keeps rising. In NerdWallet’s samples, an 8-year-old cat cost about 1.6 to 2.2 times as much as a 2-year-old at the same insurer. Those samples came from four insurers, quoting a domestic shorthair at two ages.

Sample cat	Monthly price range (4 insurers)
2 years old	$14 to $24
8 years old	$23 to $51

Cats are still cheaper to insure than dogs at the same age. NAPHIA reports the average accident-and-illness policy for cats cost $435 a year in 2025, about $36 a month, across all ages. Accident-only plans averaged $112 a year, about $9 a month. Our cat insurance cost guide covers the other pricing factors.

To lower the price, raise the deductible (what you pay each year before the policy pays) or pick a lower reimbursement rate (the share of each covered bill you get back, often 70% to 90%). Both trade a cheaper premium for bigger out-of-pocket costs when your cat gets sick.

Common senior cat conditions and what they cost

Four conditions drive much of senior cat care: kidney disease, hyperthyroidism, diabetes and dental disease. The AVMA also notes that cancer causes about a third of deaths in cats over 10.

Condition	How common	Typical costs	Curable?
Chronic kidney disease	Up to 40% of cats over 10, 80% over 15 (Cornell)	Lifelong diet, fluids and medication	No
Hyperthyroidism	Common in middle-aged and older cats (Cornell)	Radioiodine about $1,500 to $2,000 (PetMD)	Often, with radioiodine
Diabetes	1 in 100 to 1 in 500 cats (Cornell)	Insulin $25 to $100 a vial, about a month’s supply (PetMD)	Remission is possible
Dental disease	Early gum disease likely by age 3 (AVMA)	Cleaning $113 to $600 in 2023 (PetMD)	Treatable

Kidney disease

Chronic kidney disease affects up to 40% of cats over 10 and 80% of cats over 15, according to Cornell’s Feline Health Center. It has no cure. Treatment aims to slow it with special low-protein, low-phosphorus diets, hydration support, and drugs for related problems like high blood pressure. Advanced cases may need regular fluid therapy.

Early signs are easy to miss, so it is often found on routine bloodwork. Cornell notes that cats diagnosed at IRIS Stage 2 average two to three years, while those diagnosed at Stage 4 average under six months. Because care is lifelong, the bills keep coming every month.

Hyperthyroidism

Hyperthyroidism is a common disease in middle-aged and older cats, caused by an overactive thyroid gland. Cornell lists four treatments: daily medication, radioactive iodine, surgery and an iodine-restricted diet. It calls radioactive iodine “the treatment of choice” and says it cures about 95 percent of cases within three months.

PetMD puts radioiodine at $1,500 to $2,000 for the treatment itself. One treatment center lists a total of $1,900 to $2,100, including a $200 consultation. Medication is the cheaper upfront choice, but it is usually given twice a day for life.

Diabetes

Cornell estimates that between 1 in 100 and 1 in 500 cats are diagnosed with diabetes. Age is a risk factor, and obese cats are up to four times more likely to develop it. Treatment usually means insulin shots about every 12 hours, plus a low-carbohydrate diet. Many cats reach remission if treated early.

PetMD lists the ongoing costs: insulin at $25 to $100 a vial, with each vial usually lasting a month. Vet visits run $30 to $120, and blood and urine tests $50 to $100. These are the kind of repeating bills where medication coverage matters; our medication guide explains how insurers handle prescriptions.

Dental disease

The AVMA says periodontal disease is the most common dental condition in cats, and most pets show early signs by age 3. PetMD found cat teeth cleaning cost $113 to $600 in 2023, with more charged when damaged teeth must be removed. Our dental coverage guide explains why dental illness and routine cleaning are treated differently.

Pre-existing conditions matter more for older cats

A pre-existing condition is any problem your cat showed signs of, was diagnosed with or was treated for before coverage began. Insurers exclude these. For a senior cat, that rule matters more than the price.

Insurers sort pre-existing problems into curable conditions, which fully resolve, and incurable ones, which never count as cured. Lemonade’s guide lists chronic conditions such as cancers and endocrine (hormone) diseases as incurable. Kidney disease, diabetes and hyperthyroidism all fall in that territory, since kidney disease and diabetes are chronic and hyperthyroidism is a hormone disease. If any of them is already on file, expect it to stay excluded.

Curable problems are different. Some insurers will cover a resolved issue, like a bladder infection, after a set symptom-free period, often 12 months. Our pre-existing conditions guide covers how insurers read your cat’s records.

This is the strongest argument for enrolling before signs appear. A cat insured at 9 with clean bloodwork can have kidney disease covered at 12. A cat enrolled at 12 after a high kidney reading cannot.

Is accident-only insurance enough for a very old cat?

Accident-only insurance is cheap, but it will not pay for any of the conditions above. An accident-only plan covers injuries like falls, bite wounds and swallowed objects. Kidney disease, hyperthyroidism, diabetes and dental disease are illnesses, so they are excluded.

For a cat over 15, it may be the only choice; Embrace, for example, offers accident-only cover at that age. At about $9 a month on average, it can be worth it for an indoor-outdoor cat with real injury risk. For a strictly indoor senior, the protection is thin. Not every insurer sells accident-only plans; Lemonade only offers accident-and-illness coverage. Our accident-only guide compares the two plan types.

Is senior cat insurance worth it?

Senior cat insurance is usually worth it for a healthy older cat that can still get illness cover. It is rarely worth it if your cat’s likely problems are already in its records.

It tends to pay off when:

• Your cat’s recent bloodwork was normal.
• A $2,000 treatment like radioiodine would strain your budget.
• You can keep paying a premium that rises each year.

It makes less sense when:

• Kidney, thyroid or blood sugar problems are already diagnosed.
• Only accident-only cover is available and your cat stays indoors.
• You can set the premium aside each month without touching it.

The AVMA recommends senior pets see a vet twice a year or more. Those visits are routine care, so a standard policy won’t pay for them unless you buy a wellness add-on (an extra covering preventive care). If you also have an older dog, our senior dog insurance guide runs through the same decision.

Bottom line

Most insurers still cover senior cats, though some stop at the 14th birthday and others limit cats 15 and older to accident-only plans. Expect premiums well above the young-cat price, roughly $23 to $51 a month at age 8 in NerdWallet’s samples. Kidney disease, hyperthyroidism and diabetes are the big senior risks, and none will be covered if they are already in your cat’s records. Enroll while recent bloodwork is clean, and choose an annual limit that could handle a $2,000 treatment.
