Good question! Honestly, I'm not entirely sure. I'd say absolutely no avacados and don't feed to much vit. A, but for the most part I don't think it makes a huge difference, as long as the crix are gutloaded. I'm excited to see what others may have to say on this.
In general, I think variety is good. I've heard corn can cause some problems in a round-about way, so if you are using dogfood as gutload, it should be one with a low corn content.
