I don't know how, but I swear Bunya can tell time. That has been asserted here before.
Their favorite treat, a Probios is served (for whatever reason) at 9pm. If I miss the time, Bunya will stare at me from the floor, using his mind meld to communicate his message. If I am too absorbed in my book, then he hops up on the sofa next to my recliner, where I have to see him, and repeats the stare.
