Depends whether your pet lives to a great age with no illness or accident or maybe develops a problem next week!
This is what insurance is, some protection against unforeseen costs.
Could you afford to pay out perhaps thousands for a broken leg?
Insurance will also give you third party cover so if your pet causes an accident it will pay the damages instead of you having to sell your house.
I've just cancelled mine. Getting the money out of them was just so difficult and they wrote to me with so many stupid questions that I just gave up. I was also sick of having to repeat myself to some idiot in a call centre that it just became non cost effective. I have to fork out for the treatment anyway, and then they refund it. It was so hard getting the money back I've decided that I just go it alone.
Although monthly pet insurance can be quite high for me, with 7 cats and 2 dogs, I know if I try the money in the bank method, something will happen to one of them really soon.
Although having said that, I currently dont have any insurance and need to look into getting some!
