My cat knew how to open doors. And the knobs were round too; we kept trying to figure out how she kept getting out of the bathroom each night. We then stayed up and waited one night near the door. We saw the knob turn, click, the door popped open, and she strolled calmly out. She’d twist the knob using both of her paws.
Don’t be too sure that cats don’t know how to use doorknobs. They’re clever, crafty creatures and, if they had to, might be able to work it out.
I don’t care if it was a good party or not. I wish I had been invited!!!!!!! :)
