Hello everyone - I desperately need your help…… we have 6 sphynix cats and they have bowel movement issues. 2 of them have no issues adjusting. I put them on prescription hill diet, Small, and N&D. They all had tested for parasites and other stuffs, all are negative. So I’m so frustrated, I would love for them to have Normal bowel movements and no more of this. Any advices and what foods should I put them on, I would appreciate very much. Thanks
