>Ask the vet for en estimate.they should have a clear idea how much its going to cost to open her up and take something out. might not be as much as you expect. Or have you got anything like the PDSA (they do low cost vet work for people who can't afford a lot in the UK)

Yeah, we've seen estimates on the internet range from 700-2000. I would consider those manageable but I'm afraid it will be more just because I am eternally pessimistic.
