Hey Too, have you tried the George's distilled aloe juice? It looks just like water and I just tasted it--tastes like water too. They've got a website you can look at, if you're interested. That's the stuff I spray on Morgan for her itchies.
I use the cornstarch also, but I also had an incident where I cut a gouldian finch's nail and it started bleeding--couldn't find the corn starch and as a last resort stuck the little one's whole foot in my sugar bowl. Not that I use much granulated sugar except for holiday baking so it was probably due to be tossed out anyway. Bit unusual, but it did work.
