Julie, BJ, lu-Ann, Marilyn, Sandy. Thank you all for looking in late last night after I had gone to bed and for your support and advice. Was a bit panicky again this morning and didn't have time to read everything properly before testing and trying to get Crystal to eat. With guidance from Wendy and your comments I decided to miss this morning's shot. She has since eaten about 90 per cent of her normal breakfast, once I warmed it up for her. No action in the LB although she is trying. Now sleeping (wish I could). Will talk to my vet in a few hours, only trouble is she knows zero about acro but will ask about megacolon, and miralax. I will post later with any developments, thanks once again. Lu-Ann, hope you are feeling better now, take care.
