You can get specialist pet insurance for your cat if they have a pre-existing medical condition. This type of policy is designed for those whose pets already have a medical condition before they take out an insurance policy. While you'll be able to take our standard pet insurance if your cat has a pre-existing injury or condition, it's unlikely that your insurer will cover veterinary treatment for that particular condition - as there's a risk that the condition may flare up again. With this in mind, if you want to cover veterinary treatment for your cat's health condition, you'll need to get specialist pet insurance for pre-existing medical conditions.
