Aminopterin, melanine and what else?

We don't know much about what's likely killed hundreds, or thousands, of us pets. Aminopterin could not be isolated from pets,
Melanine is in the Chinese gluten, but it's not supposed to be nephrotoxic. The focus is still on the Chinese gluten (which apparently has lots of fun ingredients), but maybe it's not the gluten after all. A dry cat food has also been recalled.

I hope Homeland Security is paying attention.

In the meantime, my personal conclusion that our family needs to switch to human-regulated foods for our dog stands.
