After 4 hours of grappling about a third has been nibbled off and pulled up, about a third similarly nibbled off and gone past the sphincter into the stomach, leaving a flower end disc which wouldn't go either way.
So they've brought her round leaving this nibbled bit hoping it's roughened surface and her saliva will ease it into the stomach.
That or she'll puke it out as vomiting is more powerful than swallowing.
Hopefully we get her back tomorrow, if she's still distressed other options will be considered. She is able to walk but disorientated.
