Hi all. Thanks to all of you for your responses. She is still pretty bad on her legs, like those poor cows we see with CJD. I'm convinced she's got something nasty behind the eye and cats4eva, you have a very good point there.. I'll keep you all posted on the thread, it's a learning experience for us.
She's not in any pain but her quality of life is not good. She tried to cross the garden earlier and fell on her side, poor thing.
