Depending on what type of lifetime pet insurance you have, you can claim for the same condition each year.
Some policies set a limit on how much you can claim in a year. Say this is £6,000 – if you go over this amount you’ll have to pay for treatment until you renew, when you’ll get £6,000 of cover again.
Other policies set an annual limit per condition. So, if your limit was £1,000 per condition and your cat had an infection that cost £350 to treat, then diabetes that cost £1,250, the first illness wouldn’t affect your second claim. But you’d only be able to claim £1,000 for the diabetes.
