I didn't go to the link, but did want to say . . . there's nothing wrong with feeding crickets to cats. I'm sure ferals do it.
This part of the quote bugged me (no pun intended):
Personally, I am concerned about the future of our planet and the resources needed to provide high meat diets to our dogs and cats.
It sounds like this person would seriously consider feeding carbs/kibble to save "resources." I hope not.
