I have both, and use the credit card to pay for things until the insurance pay up. I also started taking £20 a month up last year to pay for their annual bloods and boosters (I would only claim for bloods if it showed something, as it is for my piece of mind, not a vet recommendation), but with heavy vets bills, I let it slip, so only got part of the cost of Molly's bloods and boosters next week. I probably woud be best putting it in my savings account, but the advantage is that it is at the vets, so if something unexpected happens, I have something there. Rolo's dental will end up going on the credit card, and I shall just have to reduce the money going into my savings to pay for it.
