Jojo is a cute name. I'm glad she's still hanging on. The syringe is a good idea, it will help her out a lot with drinking. She might be in a bit of pain but if she still has the will to eat/drink then she's still trying. I wouldn't have the heart to put her down unless there was no hope whatsoever. I would tend to her for as long as you can or until you think things will not get better. I wish her and you the best of luck.
