There is a direct link between proper hydration and liver and kidney health and the more we study the subject, the more we find out how important it is. So, please, reconsider giving your parrot pellets, dehydrated/freeze-dried/dry anything! Nature evolved them to eat a diet that is 85 to 95% water (raw plant material!) and to drink just a little once or twice a day so anything dry is bad for their kidneys AND their livers!
