I have some questions about what I suspect to be parasites...Last night as I was cleaning cages, I saw one of my two year old girls deficate. It did not look normal. It was watery and lose and the color was light tan. Upon inspection, I discovered little strands in it. I do not know if these were undigested bug parts or not, but they looked like small worms to me. This gecko had been losing weight but I thought it might be due to the fact that the other 2 females she is housed with were intimidating her. She is alone now, but I need to know what I should do from here...Is it safe to treat all of my geckos for parasites? I don't want to take the chances of any other animals aquiring this, as they are all housed rack style. So my questions are:

1) Does anyone recognize this type of illness?

2) How is it treated?

3) Is it safe to treat all geckos as a precaution?

Thanks in advance.
