Thank you for replying.
Yes, it's the drop in blood sugar that really worries me. I'm not going to starve her, it seems much too risky to me.
After reading lots of posts previously on here, I've tried to buy Pepto & Nutrical to have in stock for emergencies, but unfortunately I can't get hold of it over here. I've just rung the pet shop in my nearest village to see if they just happened to have Nutrical but they said it isn't available in the UK. Don't know if I could get it shipped but that wouldn't help today. all they could recommend was Lactol, but that's no use as it's just a bitch milk replacement.
So I think I'm going to give her chicken & rice once it gets to her lunch time & hope for the best, but i'll keep checking on here for any more suggestions.
Thank you again for your help. It's a real comfort to have you listening & helping
