Well, if there is any good news in this its that they are coming tomorrow.
I know what you mean about trying to find someone. I looked in yellow pages too - nothing. In the end I phoned animal welfare in Carmarthen as they have an out of hours vet you can call and he gave me the phone number.
They were very good with my pig last Sat and the man and my OH dragged the pig to the lorry between them. I stayed out of the way. It isn't a nice time but you will feel a bit better when she has gone.
