oh goD penny, didn't realise it was happening so soon - huge hugs to you and Ruby
I don't think she'd be in much pain at the mo - the whimpering etc will be GA wearing off. I hope she'll be feeling better in the morning.
I know this is for the best, and she will cope brilliantly as she is feisty and strong, but I also know how dreadful I would feel if this were to happen to Jarv - so sending many hugs and strong thoughts to you both.
She will feel so much better in a few days and will be as beautiful as ever I'm sure
