Thank you Willow and Waterloo Update below!
Jane I wondered about that, too (the purring), but it sounds as though it was proper purring and she enjoyed the attention the Vet Nurse was giving her and was responding to it. Perhaps I'm being optimistic!
Today's Vet told me that a tube had been passed down her throat to check it when she was admitted before (last week) and her mouth checked, Tomorrow's endoscopy will check again and also her stomach.
She's salivating a lot, which could be stress or because she's trying to avoid swallowing. I remember when I had to be 'put out' to have all four of my wisdom teeth out and my throat was so sore afterwards that, rather than try to swallow, I put a huge wad of tissues on my pillow and dribbled all night
She's still very alert and being given fluids and meds intravenously. No food, so I can't imagine how little she weighs now! She was only 2.8 kg when she was admitted.
Fingers crossed for our little fluffkin tomorrow evening when they'll do the endo!
