For the longest time, getting Watchcat Sammy to meow when I recorded video of him was a challenge. As soon as I stopped recording after several minutes of silence, Sammy would start meowing up a storm. Occasionally, I was lucky enough to capture footage of him speaking. Often, however, I felt like I had to put asterisks on videos I'd filmed, such as, "After I stopped recording, Sammy let out a triumphant, elongated 'Meowwwwww!' before sprinting across the room," "Just before I recorded this, Sammy squealed excitedly while zeroing in on birds in a tree," or "Right after I stopped filming, Sammy set up a lectern and recited the Gettysburg Address."
To be honest, I might just have imagined that last scenario.
