Fafnir loves playing with hair ties. Which is also why I’m constantly losing mine. Anything left on a counter or floor is fair game. From time to time, I pull up the couch cushions and find a little hoard of them.
Later I’ll go dig up my videos of him playing fetch and playing by himself with them, but for now, here’s Fafnir playing with one I hooked on the leg of a chair.
