Evo and canidae?

[jupiter11600]

I'm just wondering if it is all right to feed wiggles Evo RM and Canidae (The chicken&Rice)

We feed barry and sierra canidae as it is a great food on a good cost and so far they do well, But wiggles needs all the oomph he can get for food so he has been on Evo RM. At over 3 cups a day, evo goes fast! So I am wondering if it is all right to feed him 1 cup evo in the morning, and then 2 of canidae at night.

Thanks in advance,
