Someone on this forum once referred to a cat pushing something off a shelf, desk, dresser or table as 'checking gravity'. Well, Lynx had a failed test the other day. He chose to push my daughters headphones off her computer desk. The headphones were plugged into the computer speakers. When the final push knocked them over the edge they only went about half-way down and just dangled there. Lynx just sat there and stared. And stared. And stared. He finally looked around and found something else to push. When that hit the ground he jumped down and, totally ignoring the dangling headphones, walked out of the room with his head and tail up in the air. I swear my hubby and I were laughing so hard. I have never known that cat to not bat at something like that dangling. But he wouldn't even look at it.
