Spiky projections on plant matter may act like “drain snakes,” helping felines dislodge wads of fur



Summary

Cats sometimes ingest fur while grooming, leading to hairballs. New research suggests that spiky projections on certain plant matter, like grasses, may serve as a natural solution. These projections likely act like “drain snakes,” snagging and pulling ingested fur from the cat’s digestive tract as the animal vomits. While not definitively proven, the hypothesis offers a plausible explanation for why cats instinctually chew on rough vegetation despite not deriving nutritional benefits. This behavior could be a clever, evolved strategy for managing uncomfortable and potentially harmful hairball buildup.
