A Sudden Tap

My paws twitched and my neck stretched right up! I couldn't sit still—everything felt buzzing and awake. Right behind me was this giant, tilted yellow lid forming a funny little slope. I leaned over, reached out one paw, and gave the hard plastic a firm tap. It made a sharp clack! I hopped back slightly onto the soft bedsheet, staring at the hollow space underneath it with wide, eager eyes.
