My vet has given up on Cilla so time to call it a day, he thinks that her kidneys have packed in and even giving her antibiotics will not get to the underlying problem, she now has a temperature, will not eat or drink and I can't bear to think she may be suffering. I feel such a failure, I know I was rearing her for the freezer, and she was due to go last week, but that does not make me feel any better. Thanks to all who offered advice etc. There are so many really nice people out there.
