Shiny thing is mine!
Goes in my lair with house keys.
You didn't need those.
Human enters room,
I'll hide behind the sofa.
Oh, food, changed my mind.
Can't get down from tree,
grown taller since I climbed up!
Next tree looks shorter.
Hidden box of toys!
Coloured worm goes everywhere.
What is this "knitting"?
Scratching post gone,
I'll use furniture instead.
That's what it's for, right?
There is a collection of similarly-themed senryu here.
