Did they give you anything for your Stedman? Usually they will treat everyone in the household since they can catch it pretty easy....if it was me I would call them up tomorrow and ask if you should give him anything too. Good thing you were watching out for her!!
I think this thread is wonderful and really shows what to watch for. I have heard that coccidea is getting worse as the winters are getting less everywhere and isn't killing it off. So it's great that people are aware of it and although the photos isn't the nicest - it is a classic sign!
