Found parasite or undigested food in stool

[Homebody]

I was cleaning my boys bin when I saw something weird in his poo. The poo itself seemed like a lot more than usual, and on the soft side. BUT the gross thing that was hanging out of it... looks like a twisted up rubbery noodle that tapers down. I have an image link posted but forwarning, it's kinda super gross.

I checked his vent and he seems just fine but I'm worried he has parasites. My only other guess is that it's some undigested piece of central nervous system from his last meal. What should I do?

I saved the nasty rubber noodle wrapped up in case a vet needs to see it.

If your bp is otherwise acting normally and appears healthy, I'd wait to see if it repeats. I'd start weighing him, so I could keep an eye on that. If it repeats, his weight drops, or he begins exhibiting any other concerning behavior, I'd take him to the vet.
