Received an email today form J, the lady who had adopted and returned Genie and Silver. Her 12 year old cat suddenly became ill and was hospitalized. She later died of kidney failure and J suspects the Nutro food (pouches with chunks in gravy). The cat was fed with various types of Nutro pouches and Nutro dry food (salmon).
My cats are all eating Nutro dry food, mixed with a little Natural Balance, which they don't really like much. So far no ill effects. The supplier assured me that it was safe.
