Thanks everyone for your good suggestions! As Pui Pui is still having her special diet for the next 4 weeks, I shall speak to my vet about the Apple Cider Vinegar next time I visit her.

The first thing I will do it is to try different kind of water bowl. I have a feeling that she will prefer a flat plat.

Troy, "Pui Pui" is Cantonese. I had a Lutino (mini-Cockatoo in white) name as Po Po before I have Pui Pui. In Cantonese, "PoĦ¨itself means "treasure" while "Po + PuiĦ¨ means "my honey".
