I am really glad to see the updates
I am a home cooker as well. I do have some concerns about the recipe though....A lot of the ingredients I would never feel comfortable feeding.
If you are ok with homecooking I would consult a Pet Nutritionist.
Susan Davis is highly recommended here on YT and the consult and diet she prepares are not only healthy, holistic and natural, they are also balanced properly, which I am sorry to say, but I do not feel the recipe you were given is balanced. I also believe that Susan Davis is pretty reasonable with her fee.
