Thanks again for all the well wishes.
I think they must be working... She's had a little drink of water and has, unprompted, eaten a few mouthfulls of chicken breast. I think the steroids are kicking in now so hope to see more improvement by tomorrow.
I was so worried earlier, I really thought she was dying when I saw her vomiting like that. It wasn't like 'normal' sickness, she was foaming at the mouth, the mucus had blood in and was really stringy and she was trying to wipe at her mouth with her little paw, this all happened under the bed - I didn't want to drag her out mid wretch, I just felt so helpless. I know that she has reached a good age but that doesn't make the thought or reality of losing her any easier
