This was right out side of one of my cats litter boxes...what in god's name is it? Something that came out during bowel movement? Perhaps the remainder of something my cat caught and ate? I am so grossed out and not sure if I should be concerned. My cat seems fine. Not acting like he doesn't feel good. It being right outside of the litter box worries me though. As anyone every seen anything come out of a cat that resembles this?
