“I saw some of these worms in my cat’s fur, near his butt, but I’m not sure if it’s a parasite or just something from my garden”, writes Th?o in their submission regarding the black, worm-like organism pictured below. “It’s very small, like 5mm long, and very lithe. It’s a pinkish color (it looks darker in the picture). It also died (or dried out) soon after I found it, about 10-15 minutes later. We live in south east Asia, where there’s a tropical climate. Thank you for helping me.” To start with, we have to say that, whatever suggestions we make as to the worm’s identity, Th?o should take them with a grain of salt. The reason for this is that, since this worm was found on Th?o’s cat, it is possible that this is a medical situation.
