Thank you for your replies. I did take a sample to the vet today when I went to pick up 2 young fareals that were spayed. It turned out to be coccidea. The vet said he didn't see a lot, only a few. He gave me some medicine to give them and the kids took the first dose extremely well. I tell ya, this fostering/rescuing is a job in itself! Hats off to those of you who have been doing it a long time! God Bless ya!
