Hi MC,
If you go to the ibdkitties site, I think there's a "contact us" icon you can click to email her. She's putting together a list of the foods that have spinach in them, and she can contact Dr. Pierson. You can also contact Dr. Pierson directly via her website, catinfo.org.
I hope this helps!
Thank you I'll do that. I was about to try the natural balance pouches, but guess what, they have spinach, too.
