Cleopatra, do you have Argos over there? I have Maxx insured with them and imho they have been excellent.
Maxx has been diagnosed with SM so we paid the first Â£50 of the first claim when the tests began and then ever since they have paid the full amount of every claim as it is a continuation.
A lot of pet insurances won't do this. Another good one is the one through your Vet.
One thing I will say is that, unless you are extremely rich, pet insurance for a Cavalier is a definite must!!!!! Also, get the best policy you can afford. I have the Platinum cover for Maxx and it is only about Â£3 more than the basic but it gives me something like Â£4000 worth of cover - just as well when you think that this years medical bills alone have been over Â£2000 so far....
