Re: Color of parasites?

This reminds me of something that happened last week to my cat who is still young and playful. She was walking kinda funny in little circles and looking behind herself. Anyway I saw this long thread coming from her derriere and wondered if she managed to get into my stash of Humaworm and was passing a parasite? butt no that wasn't it at all. She had swallowed a piece of dental floss!
