Definitely get them insured!!! I paid over £1000 in total for Pebbles last year, and Sainsbury's paid out every single claim (4 different claims I think) - there was only one query, and that was cos she had seen two vets, and the claim was from teh second. They can be a bit slow, but they do pay out, so I use the credit card to pay for anything expensive, knowing I will only have to find a small percentage of it.
