My greyhound ran into a pole and tore open his knee. I had gotten insurance for the "just in case" of this very situation. I live in an area that's more expensive than "customary," so the original friend who recommended that I get pet insurance warned me that it would reimburse about half of vet charges in the area.
The process to get reimbursed was easier than it is with my human healthcare FSA! I received my check about 2 weeks after I submitted the claim. The grand total at the vet was $480, and I ended up with a check for $240-- just what I expected, and still a financial relief.
