Thank you everyone for the wonderful support! My By Nature contact has been trying to help me too, with other brand suggestions. Unfortunately they are all brands I have already researched.
Apparently they have no plans to discontinue the By Nature Organic Chicken so I am going to try transitioning Mazy to that. Mazy has strict limitations, for one thing, but she also cannot tolerate variety. That's the big issue for her. I can't feed her a wide range of foods in the event that her food disappears, because her body just cannot handle it
I used to give her the By Nature Organic chicken but it didn't seem to agree with her. I thought it was the liver. Maybe it was just because it was variety. Once she is on it and only it (along with the Rad Cat) maybe it will be okay. I have about 7 cases of the chicken&turkey so the transition can go very slowly. I just hope doing a slow transition is the right way to do it, since it means more variety. Rather than an abrupt change leaving her eating only the new food I mean.
If I am making any sense.
Feline's Pride is not organic and contains bone, and she does have the Rad Cat raw (organic and uses organic egg shell calcium). Evangers, I won't touch it, and in fact will not be buying Wild Calling again (for the other girls) because WC uses an Evangers plant and has no plans to change (I wrote and asked)
According to Becky (my BN contact) they have no plans to bring back the turkey&chicken or the turkey&liver.
I am going to have to come up with other foods for Queen Eva and Jennie, especially Queen Eva, but their requirements are not so limited. They can eat non organic. My biggest problem there is Queen Eva is a finicky little thing. I am trying her on the Tiki again. In the past, the Thailand foods have given her diarrhea, but desperation has made me try again. She likes the Tiki, and so far I've only given her tiny servings of it.
I've got to go reading Dr Pierson's list again, to find some lower carb foods to try for those two
