Living with a dog, a cat or a rabbit carries a cost that almost nobody works out fully before adopting. Food and litter show up every month, but veterinary spending is spread unevenly: quiet years when you barely set foot in the practice, and then one in which a single invoice exceeds everything you spent in the previous five.
Planning for it is not about guessing what the future will cost. It is about separating what is predictable from what is not, and deciding calmly how you will meet each part. This guide sets out the two blocks and explains how the arithmetic changes once pet insurance is in the picture.
The predictable part: your routine annual spend
The stable half of the budget is preventive medicine: the annual check-up, the vaccination schedule, internal and external worming, and microchipping if the animal is not yet identified. These costs are moderate, repeated and easy to anticipate because you know about them months in advance.
Prices vary by region, by city and by type of practice, so it is worth asking your own practice for its price list: it is published or available on request, and comparing is entirely reasonable. As a reference, our own guide to vaccination prices in Spain puts a full first-year course at between 100 and 180 euros for dogs and between 90 and 150 euros for cats, while annual boosters for an adult animal come to somewhere between 40 and 90 euros depending on which vaccines it needs.
On top of that base come the costs specific to your animal. A breed prone to skin problems will need medicated shampoos and more frequent reviews; a cat inclined to urinary trouble, a prescription diet; a rabbit, a vet experienced with exotics, whose consultations tend to cost a little more because of the specialisation. All of this is foreseeable and fits in a monthly budget.
The unpredictable part: the invoice you did not see coming
The second block is the one that catches people out. A gastric torsion at three in the morning, a swallowed foreign body, a cruciate ligament torn jumping off the sofa, a road accident, kidney failure picked up in a routine blood test. None of these appear in a diary.
Nor does the cost resemble the routine. An X-ray or an ultrasound is counted in tens of euros, but several days of hospitalisation, spinal surgery or a long course of cancer treatment are counted in thousands. And in those cases it is not only the amount that weighs: it is the speed at which you have to decide.
That is the moment when families find out whether their financial plan was realistic. Not because they were unwilling to spend, but because the money was not available that same week. A clinical decision made on the basis of liquidity rather than veterinary judgement is the worst decision available.
How a reimbursement policy changes the arithmetic
Pet insurance does not remove the expense: it turns it into a predictable monthly premium and shifts the risk of the spike. With a reimbursement model like Petplan’s, you go to the vet of your choice — there is no closed network — pay for the treatment and then send in the invoice and the clinical report to claim it back under the terms of your policy.
Petplan’s policy reimburses 100% of covered veterinary costs, with an annual limit of 3,100 euros and a 45-euro excess applied per illness, not per visit. That distinction matters: a condition that needs four follow-up appointments generates one excess, not four.
Premiums start from 0.70 euros a day. As a guide, a cat can be insured from around 16 euros a month, a dog from around 23 and a rabbit from around 18, depending on age and circumstances. Set against the unpredictable block, the premium is the small part of the equation.
The numbers worth checking before you sign
When comparing policies, three figures decide almost everything: the reimbursement percentage, the annual limit and the excess. Reimbursement at 100% with a sensible limit protects you more than 80% with a high limit you will never reach, because the remaining 20% of a 2,000-euro invoice is still real money leaving your account.
Check the waiting periods too — the time that must pass between taking out the policy and cover becoming effective. With Petplan they are 15 days for accidents and 30 days for illness. Buying cover once the animal already has symptoms does not work: pre-existing conditions are excluded by this and by every other insurer on the market.
Finally, look at the extras that add a lot without adding much to the premium. Third-party liability, covering up to 300,000 euros a year for around 25 euros annually, answers for damage your dog causes to others. And the optional vaccination cover, up to 90 euros a year, includes the leishmaniasis vaccine, which matters across much of Spain.
Saving on your own, or insuring
Putting money aside each month in an account earmarked for the vet is a legitimate alternative and works well for routine spending. The problem is the calendar: your own fund protects you from year three or four, once you have built a decent cushion, but leaves precisely the first years exposed.
An accident does not wait for savings to mature. And in young animals — the ones most likely to swallow something, land badly or bolt after something interesting — the risk is concentrated in exactly that early period.
So the honest comparison is not “insurance or savings” but “how long until I have several thousand euros available, and what do I do in the meantime?”. Many families do both: a modest fund for the routine and a policy for what no fund can absorb.
Plan now so you can decide calmly later
The point of working out veterinary costs is not to frighten yourself with numbers. It is to arrive at the difficult moment with your options open. A realistic annual budget for prevention, plus protection for the unexpected, means the conversation with your vet is about what suits your animal rather than what you can afford that week.
If you are considering cover, take it out while your pet is healthy and the waiting periods run in your favour. That is the moment when the decision is pure planning rather than a race against a diagnosis.
