Well forgive me for sounding harsh, but your 10yrs of bunny ownership hasn't exactly taught you much has it. With all the thousands of lovely bunnies already in rescue, and the terrible ordeals god knows how many of them have been through, you're just the type of nightmare the hardworking rescues dread, bringing even more unplanned bunnies into the world. No one is saying that every doe will develop uterine cancer, but most of us care about and love our bunnies to much to take our chances when there is over an 80% risk of it happening. You obviously weren't using an especially knowledgeable rabbit vet, because rabbits don't get overdosed with anaesethic, but the majority of vets don't know how to maintain the buns airway or intubate them, and then problems arise, and by the time they have got an airway in, the bunny has gone. Personally I think all bunny owners taking their buns in for surgery, would have a very good indication as to how knowledgeable their vet is, if they asked if the airway is maintained or not, and if the reply is 'not', hop away immediately!!
