Nadine,
I’ve never researched into this to be honest. I think part of the problem with feeding kibble is there is so much to look into and there’s always going to be something about it that isn’t ideal for our pets . I suppose that is why people end up feeding raw or home cooked. I looked into both and I’m just not ready to try raw yet, and want to research more about making a balanced meal for home cooked. As a result, I ads homemade to her kibble for now. I’m interested to hear if others know more about the copper issue. I’ll be following.
