WAIT! My Moon Girl Cat just went through a VERY similar thing - stroke like things - IT MIGHT BE OK This was 6 weeks ago and she is getting better. It was some sort of inner ear BAD infection and she may never be back to her old self but she is soooo much better and is eating and actually playing with her "own things that play in the dark" . I don't know if this is Ebie's problem but if it should be...have faith. She still walks a bit sideways but Moon girl has adjusted enough to show the other guys to still give her space and the respect she deserves. She is still the matriarch after all.
