Hi, I am helping out a Cat Resuce place. We have a little kittne who was found abandoned on the road infested with maggots. While the maggots were all removed and he seed to be doing fine, he got coccidia. His fecal turned out negative to coccidia in the bgining, but yet he was given albon as a preventative measure. a week later he had runny stools. He was put on albon again and given marquis paste. He then seemed to be doing better. But a week later, once again runny stools. He is about 3 months old now. We will be giving him antibiotics - primor sulfadiazine. Has anyone experienced something like this ? where niether albon nor marquis paste is killing the coccidia ? He tested negative for giardia yesterday. Thanks for your help.
