If your cat is insured it’s well worth keeping up with that insurance as it becomes more likely that health problems occur as the cat ages. It may be too late to insure for the first time with some insurers, but it is worth checking before your cat becomes a senior. Pet insurance can be a very effective way of dealing with the extra costs associated with unexpected treatments and give peace of mind that you will be able to afford them when such events do occur.
Choosing a lifetime policy will ensure that current problems will not become uninsurable pre-existing conditions, as they might with an annual insurance (which may seem cheaper).
