“I pulled this off my cat”, writes this reader in her submission regarding the brown, slimy-looking, worm-like creature pictured below. “Can you identify it?” For starters, we will say that, while we will provide an identification, it should not be taken as 100% accurate or certain. The primary reason for this is because our reader pulled it off our cat. Any worms that are found on or inside people or pets pose a potential medical situation. Since we are not medical professionals, we are neither qualified or legally able to identify organisms that directly affect the health of people or pets. In this case, it is not clear whether or not the worm is affecting the cat’s health: people and pets accidentally get worms on them all the time, just from going outdoors. For that reason, we err on the side of caution. If our reader suspects that this worm may have come from her cat, or that it is in any way negatively affecting her cat’s health, she should consult a vet about it and disregard our identification below.
