I would say yes, definitely worth having thesedays.
As medical treatment for humans has advanced, the treatments available for animals has advanced too. That's good news if a pet gets ill, there's more chance of successful treatment, but all this comes with a sizeable cost attached. Better to pay the insurance than face the moral dilemma of whether to decline treatment on the grounds of cost and opt for the big needle instead.
The alternative is to take the view that you'll pay whatever it costs if your pet gets sick. That's fine if you don`t mind spending a couple of grand or more.
