Is pet insurance worth the money?

I have been wondering the same thing -if pet insurance is worth the money. I have a cat myself, who is strictly indoors. I didn't get an insurance for her at first, but since I heard about my neighbour's cat who fell off the balcony, I totally changed my mind! Of course it's worth getting insurance for the pets! Vet-costs are so high these days, so I believe that getting an insurance would save you money in the long run. And you don't want to risk it, do you...?
