I have Daisy insured for just less than £9 a month and I'm very glad that I do. She had an abscess operation two months ago that cost me £300 - petplan will be refunding £250 of it! Plus, she's had several illnesses/problems which have cost just over the £50 excess.
I'll definitely be insuring her husbun Jester when he arrives too.
I have savings for emergencies, but I like knowing that the insurance is there to help, especially if one of them develops an ongoing, expensive problem. I hope it will mean that I won't ever be in the position of having to chose between treatments or tests on the basis of cost...
So, my advice would be to get insurance if you do have only one or two bunnies, because the monthly cost pales into insignificance in comparison to operation / ongoing treatment costs. And you can use your savings for the less than £50 a time vet bills, vaccs, neutering etc.
I really regret not insuring my cats when they were young - now two of them have recurring health problems which wouldn't be covered by insurance if I took it out now.
If I added up how much my creatures have cost me in total in vet bills over the years I'd probably have a heart attack :lol:
