Dagan, I think you made the right decision. I have had dogs, cats, horses, all insured at various times- but not one of the different insurers ever paid out.
Petplan were the worst. The most expensive- agreed to pay out, and then informed me I should have got the dog insured 2 weeks before I met him, to be valid.
I now just pay "their" amount for 2 dogs, into a saving account, just for the animals. I also know I can get it if I need to- and without insurance, currently have £7k saved for them- which would have been sat at Petplan otherwise, and their decision on whether to give any back or not.
