Re Iams - are you suggesting our word is not good enough? Sorry, I am tired, a little cranky and there are a zillion videos out there documenting their abuse. It is what one would call general knowledge. No good pet owner uses Iams and when they see those videos and read the info, they stop. It is pretty horrific. The videos show dead beagles just laid on the floor and cats living in cages with lots of injuries and medical issues never treated. A FINE company, NOT!!
I am too tired to search for it now. You will have to take my word for it or find the documentation yourself. It is definitely ALL over the net and on web sites of rescue groups and other animal advocates. Actually, a search on THIS site will likwly bring it up because it has been discussed here often.
