No big change in her again today, she's still eating but it's still going straight through. We're back at the vet tomorrow afternoon, the biopsy results won't be back though, it's just a post-op check. Thanks for the continued good thoughts for her 
Have you got any Pro Kolin Nic? my vet gave Bailey some when she was poorly after her op it worked a treat 
I do Jo but I'm not allowed to give her anything at all other than Hill's d/d and water, I'm under really strict instructions that she's not to have absolutely anything else, I asked about Pro Kolin when I brought her home and they said no

Thanks for the suggestion though, it's great stuff!
