We adopted brother/sister kittens at 8 weeks old. The boy, Pesto, has had diarrhea since he came to us. I have tried sticking to the Royal Canin wet and Little Friskies Kitten kibble that the foster home had them on first with no luck. They are now eating Honest Kitchen wet as their main meals with Honest Kitchen kibble in between when they act hungry. Pesto still has diarrhea and on Aug 25th I started adding organic pumpkin to his food, 1 T. twice-a-day. Still, three days later, no change. He is active with his sister and has his cuddle time with me; all that seems to be normal. I'm not sure what to try next. My eventual goal, after they are fixed and totally recovered, is to follow Dr. Karen Becker's diet regimine with homemade raw. I'm wondering if I should start that sooner rather than later. Any thoughts?
