I didn't find Toto's food listed, but it is "human grade" and is dehydrated at a very low temp and considered a "raw" food. I use the grain-free formula [Force] and add a little minced chicken, fish or an extra veggie ... this allows me to control the amount of protein and add little things that she loves. The link to the site is:
www.thehonestkitchen.com .... I like the fact that it's healthy for her and easy for me .... simply add warm tap water and cover for about 20 minutes.
BTW .... I took it to our vet before giving it to her and he heartily approved it!!
