Hey, the Tassie water is different, that's for sure. Sometimes just the change of water is enough to set of gastroenteritis, but it could have been anything. Bugs are yummy! (Not that I've tried them, mind you.)
A raw food diet has to be completely balanced to be successful IMO, and that comes from years and years of research and education on the topic.
There must be a mix of chicken with other meats, organs also play a crucial part in it, but what I do see is many ppl simply feeding a raw diet of mince all the time, and it's just not correct. Raw meaty bones make up a HUGE proportion of a true raw food diet. Some feeders add vegetables, some don't. But everything has to be fed and adjusted to balance out all the ratios, so to speak.
Bear in mind that I am talking about a raw food diet, not barf diet which is totally different IMO.
