I have a cat who is constantly coming in with burrs in his fur. He leaves burrs in my bed, on the carpet, anywhere he spends time.

As he moves through weeds outside, the burrs, which have tiny hooks (like Velcro) get caught in his fur. As he continues moving - hunting, scratching, fighting - those burrs get redistributed along with his fur. Some find fertile soil while others end up in my laundry! *ouch*

Burrs, which are seeds with rough hulls that have projecting spikes or hooks, use the projections to "latch onto" passing animals or people. The seeds then "hitch a ride" on these passers by to relocate (disperse).
