I just read a class action suit filed by animal owners against Go! Natural pet food. There have several animal deaths which are being attributed to this food. The animals had a variety of symptoms but one was jaundice with liver failure. Beware of this brand. To read more, put Go! Natural in a search engine and read about this class action suit brought by animal owners against the company manufacturing Go! Natural. Foundation pet food is made by the same company, Petcurean.
