Remember that the excess is part of the cost of a pet insurance policy. You will also want to consider the premium (now and in the future) and the contribution payment if any.
Some policies will offer you the opportunity to increase the excess in return for a lower premium. See Pet Insurance Providers with Voluntary Excesses
