Insurance for a cat with pre-existing conditions or an older cat: what options there are in Spain
Many people look for insurance just when the cat is already ill or has already turned ten, and find that nobody will cover what worries them. That is the case at every company, but it does not mean there is nothing to be done. Here is what you can actually take out in Spain, according to the terms published on the insurers' official websites on 18 October 2026, and the alternatives when insurance is no longer the answer.
The honest answer
None of the insurers checked covers what the cat already had before the policy started: Barkibu, Santévet, Petplan, Petolo, Musky and Línea Directa say so on their websites in one way or another, and Petplan adds that no pet policy in Spain does. If your cat has diagnosed kidney disease, a policy you take out now is not going to pay for that disease. What it can cover is everything else: an accident, a new, unrelated illness, a different emergency. The useful question is not whether there is a policy that covers what they already have, but whether it is worth insuring the rest, and at what price.
What counts as pre-existing
More than you might think. Petplan puts it bluntly: the condition does not need to have been diagnosed; it is enough for the symptoms to have been present before the policy started. Barkibu excludes illnesses or symptoms that predate the policy. Petolo, illnesses already known and treatments recommended or started beforehand. Santévet, anything that happened or was diagnosed before the policy or during the waiting period. In practice, a bout of cystitis they had once, vomiting that was investigated or a murmur the vet noted at a check-up can be enough to exclude everything related. That is why your cat's clinical history carries so much weight when you take out a policy.
Anything that appears in the waiting period too
The waiting period is the time between signing and the start of cover: zero to 45 days for illness depending on the company, and up to six months for some specific operations or conditions. Anything that shows up during those days is excluded just like a pre-existing condition: Barkibu, Santévet and Musky say so explicitly. This has a practical consequence: take out the policy while the cat is healthy and do not wait until you notice something odd. If you take it out because you can already see they are drinking more water than usual, that illness will most likely be excluded even if the diagnosis comes after you sign.
The health questionnaire: tell them everything
Most health policies ask about the cat's condition before you take them out. Musky's information sheet, for example, sets out the obligation to answer every question about the pet's health accurately and to report any change. Keeping something quiet does not pay: Spain's Insurance Contract Act (Ley de Contrato de Seguro) allows the insurer to reduce what it pays if a declaration was inaccurate, and to pay nothing if there was intent or gross negligence, and faced with a big bill they will ask your clinic for the records. It is better to take out a policy knowing what is excluded than to pay for years for one that then does not pay out. There are products with no questionnaire, such as those from SegurCaixa Adeslas, which advertises them that way.
What you can insure
With a cat that already has a known problem, there are three things that still make sense. Third-party liability, which does not depend on their health and which you may already have through your home insurance. Accident cover, because a fall or a swallowed thread has nothing to do with their kidneys. And health cover for everything else, if the price is worth it, knowing which part is excluded. Ask them to state in writing, in the policy schedule, the specific exclusion applied to your cat: excluding "chronic kidney disease" is not the same as excluding "any disease of the urinary system". The second also rules out a blockage, which is one of the most expensive and common problems in a male cat.
If your cat is already older: the age limits
Each company sets a maximum age for taking out cover for a cat, according to their websites: under 7 at Petplan; up to 9 at Mapfre, Petolo, Línea Directa's Completo and the full SegurCaixa Adeslas option; under 9 for Santalucía's vet cover, according to its product guide; under 10 at Santévet; up to 10 at Musky; and under 11 at Barkibu. Beyond those ages, what remains is third-party liability and products with no age limit, such as the basic SegurCaixa Adeslas option (5.85 € a month, with liability, death by accident and theft, but no vet fees). The good news is for cats already insured: Mapfre, Barkibu, Santévet and Petolo keep the cat insured for life, and Petplan subject to its renewal policy.
With a chronic condition already diagnosed
Kidney disease, hyperthyroidism, diabetes, cardiomyopathy or arthritis: these are the typical diseases of older cats, and once diagnosed, no new policy will pay for them. What works here is planning the spending. Ask your vet for an estimate of what the treatment will cost over a year (diet, medication, monitoring blood tests) and divide it by twelve: that is your real insurance. Ask your clinic whether they have a health plan or membership scheme, which is not insurance but spreads check-ups and tests over a fixed fee. And if the cat has another problem that could appear suddenly, such as falls, consider cheap accident cover for that.
Adopted with an unknown history
An adult cat from a rescue or taken in off the street is exactly the case with the most doubts about what is pre-existing. The best thing is to take them to the vet as soon as they arrive, have a full check-up and keep the report: if there is a dispute later about whether something was already there, that document is your best evidence. Then, take out the policy as soon as possible if you intend to insure them, because every week that passes makes it more likely something will appear. Also look at the estimated age given by the rescue: if they say the cat is about eight, you are already close to the limit at several companies. And if they arrive with a known condition, such as FIV, assume nobody will cover that part.
Switching insurer with an ill cat
Think twice. Anything your current insurer already covers because it appeared while the cat was insured will become pre-existing with the new one, and you will also have to go through the waiting period again. If you are unhappy with the price of your current policy, first ask whether you can switch options within the same company: Santévet, for example, explains that moving to another of its options does not mean repeating the waiting periods. And if your cat has a chronic illness that is covered, check whether your policy has a time limit per condition, like Petplan's 12 months, because that changes the sums on whether to stay.
A savings pot, a real alternative
For an older cat or one with a known illness, putting a fixed amount aside every month in an account just for them is often a better deal than a policy that excludes what is wrong with them. At 25 € a month, that is 300 € a year, with no exclusions, no age limit and no arguments about what is pre-existing. Many people combine the two: liability through their home insurance, accident cover if the cat is at risk of falls, and the savings pot for the rest. What does not work is having neither insurance nor savings with a twelve-year-old cat: that is the situation in which the bill decides for you.
What to do, step by step
First, ask your vet for an up-to-date report on your cat's health. Second, check what you already have: your home insurance may cover third-party liability. Third, check the age table to see whether your cat still qualifies for any health cover. Fourth, if they do, ask two or three companies for a quote, declaring their full history, and ask in writing what exclusions they will apply. Fifth, compare a year's premium with what it would really cover. And sixth, if it does not pay off, open the savings pot today. The terms quoted were checked on each company's official website on 18 October 2026: before deciding, make sure they have not changed.
No policy in Spain covers what your cat already had or was already showing when you took it out, or what appears during the waiting period. You can insure the rest: accidents, new illnesses and third-party liability. The maximum joining age ranges from under 7 (Petplan) to under 11 (Barkibu). With a chronic condition already diagnosed, what works is planning the spending and saving.
