A couple years ago, we had guests over for a long while. Back then, a game I'd play with our two kittens was throwing dots -- dots are what we call the Blue Buffalo kibble, you see.
The kittens loved it. Chasing prey! Eating prey! Wheeeeeee!!
After our guests left, the kittens were full of energy, and I threw too hard: the dots escaped and went hurtling down the stairs. Ooooooooooh! said Digger and Misty, and promptly hurtled after them. I promptly blamed our guests for this--
Thus the "stair dot game" was born. :D
I'd have to go down the stairs to rescue the lost dots. Once I ran out of steam, each kitten would get to snarf up the leftover dots in a bowl. Digger would try stealing it from his sister too. The pawsy squirt.
