Martin, for years now, has been on the ZuPreem Avian Entrees. I have ordered it from Northern Parrots in the past but, just as the last bag is running out, I have learned that the AE have been discontinued and thus I pretty much have no way of getting these in the UK anymore!
I purchased the ZuPreem natural pellets off Northern Parrots, which should be arriving in a few days. Hopefully Martin will like them as sadly this will be a "shock" diet change...as soon as the bag of the Avian Entrees runs out (probably just as these new bags arrive!), he will have these new pellets, and there will simply be no choice really!
