How is this different from any other kind of insurance? If I live in a landlocked, arid country fifty metres above the water table, but I think an extreme weather event is about to occur, what's wrong with an insurance company insuring me against flood damage?
$135 to look after a domesticated animal for the rest of its natural life is an absolute bargain.
Edit: Not that I mind the downvote, but it's a legitimate question.
For similar reasons, I disapprove of laws requiring owners to buy insurance to cover dog bites by their dog, if and only if it is of a certain breed (pit bull, Rottweiler, etc.).
If other breeds are comparatively harmless, their insurance should simply be less. Breed-neutral insurance laws would also be more responsive than legislatures to tracking signs of risk (such as having an unneutered dog) and newly popular fighting breeds, etc.
I agree, insurance for rare events ought to be cheap.

Having thought it over, I'm OK with the ethics of this service.
