Why do cats knock things off tables?
Tiger has been researching this for six years, mostly at night, mostly with your favourite mug.

TIGER'S REPORT
I've been investigating this for six years. My method is simple. Find something near the edge of a table. Look at the human. Push it, very slightly. Look at the human again.
Every single time, the thing fell. Down, not up. I tried this over four hundred times, with mugs, pens, a set of keys and one small plant. The results were consistent: gravity is real, and the human makes a noise.
The noise is important. If I push the pen and nobody reacts, the experiment has failed and must be repeated. If the human jumps up and says my name, the experiment has worked and must also be repeated.
My conclusion: the table was too full. I was helping.
“Tiger's research was thorough, loud and expensive. The mug I pushed off the desk was a separate matter and was, I maintain, already falling.”
