Thank you everyone
We have no idea as to the cause of Big Libby's illness today. But thankfully she is doing quite a lot better now
When it started I found her lying down covered in wee, breathing VERY fast and with her head stuck up in the air. She had eaten and poo'd LOADS less than an hour prior to me finding her so ill. The pain was located around her distal colon.
Anyway, at the moment she is doing OK but I dare not be too optimistic for fear of tempting fate
