I really don't think it had a connection, but we're going to switch back because of the strain on the kidneys. Abyssinian cats have kidney problems in their breed line, so I don't want to add insult to injury. Once I heard that one of her(Juni) kidney numbers was on the high side, I knew the food had to be changed.

I didn't think about the kidneys when I switched them to the Blue Buffalo. Oh well. It doesn't cause disease, it is however, high in proteins.
