Headscratchers / Nature Cat

• In the opening theme, Nature Cat says that when his family leaves for the day, he turns into a Funny Animal. How long are his owners gone everyday? What if they get home and notice if he's missing?
  • He's a cat. Indoor-living cats that aren't feeling social and/or hungry usually find places in closets, behind or under furniture, or in cozy nooks between objects where their humans can't find and pester them.
