Butter took a month to fully adapt to his first bag of Canidae All Life Stages(production date:May 2007), somehow he had to do it again with 2nd bag(production date: June 2007). He had eaten the 2nd bag for a month to produce solid poo.
Comments from another forum:
The pattern is that they(canidae) seem to avoid answering what they perceive as uncomfortable questions. I don't believe for a moment that they didn't get my letter in the mail and my email didn't go through, since in response to an inquiry I made a while back they sent me a form-letter reply (which didn't answer any of my questions, but oh well...), so they did at the very least get that email.
Hopefully, they give satifactory response to this problem.
