In the evening, I went into the bathroom and found this on the floor.

By the time I was close enough to see the texture, my skin was crawling. It looked dry yet fluffy, as if it had once belonged to something alive. My mind cycled through every horror: some mutant insect cluster, a rotting animal, a nest of something that would suddenly burst into motion. Then, like a light switching on in the middle of a nightmare, I remembered the one creature in the house capable of such chaos: our cat.

With that thought, everything snapped into place. The “monster” on the floor wasn’t a parasite colony or alien cocoon. It was almost certainly a squirrel tail, dragged in as a proud trophy from the yard, the pale specks just seeds and burrs tangled in the fur. Standing there in the bathroom, broom in hand, I felt my fear melt into shaky laughter. It hadn’t appeared from nowhere; it had a perfectly ordinary, if slightly gruesome, explanation.
