Pet insurance as gone through the roof because most vets are rip off merchants. The first thing they ask you is, have you got pet insurance, so they know if their able inflate the bill. And in my view responsible for many of the strays dogs/ cats on the streets because people can't afford to have them treated, so they dump them.
While I respect that vets have spent a long time training, it don't give them the right to print money. My cat had constipation, I had to treat by mouth with a common liquid that's used on humans too so it was nothing special, cant think of the name just now but they were charging me £4 for a 10 mil bottle, until I found out from a friend of mine that I could by the same product from the chemist at £5 for a 50mil bottle. Total rip off.
