gluten-free Cat Food For Constipated Cats in Gluten-Free Foods, Products, Shopping & Medications Posted July 5, 2015 · Report to Admin Thank you, everyone, for the advice. I may ask my vet for an alternative, but if she doesn't have one I'll just continue doing what I'm doing and work to decrease my anxiety about it. Thank you for sharing your experiences. And bartfull - very sorry for your loss. I'm sure that you had given her a wonderful home and that she lived a very happy life.
