Yep as soon as they need admitting the price goes up by at least £100
To be honest I do sometimes wish that vets would give a realsitic rough price as it is a huge amount of money when the prognosis is so poor
In future, should you have any more buns get the vet to let you have some metacam and metaclopramide to keep in the fridge. 1st sign of any gut motility problems you can get some into them before heading to the vet. Since doing this I have pulled every one of mine through stasis without admission.
RIP little bunny
