I love how cats have such a helpful nature, and looks like you have got a really good helper on your hands. it reminds me of that commercial for diapers where she talks about how they are spoiled and they have a hair dresser, a cook, a gardener, etc. when its all the kids "helping".
Mine like to think they are helping, when I clean the litter boxes they think it's something amazing.
And they can beat the heck out of a feather duster
