Chronic Diarrhea

Chronic Diarrhea

Hello, I have 6 foster kittens, ages 9 weeks to 16 weeks that have had diarrhea for several weeks unresponsive to Albon, Amoxi-Drops, Cefa Drops, Clavamox, yogurt, acidophyllus, rice and Pres.Diet ID. Nothing helps. Fecal specimens have been negative for anything other than increased bacteria. Their stool is very foul-smelling, frequent and yellow with no form. They are growing well, however.
