As I am not currently living with the catos now for almost two months (that all changes next week!) I am only going on hear-say but I was told of a tale of Duncan that was not a big surprise.
Adam’s dad opened the window to enjoy the spring breeze, not realizing that there was no screen in the window. After living with Duncan and knowing he can sniff out a protein drink from across the house and can move with the speed of the Roadrunner once he hears a door or food can being opened, I know not to trust him. Adam’s dad, however, is just an innocent bystander in Duncan’s world and didn’t realize that this window situation might be a problem.
Duncan quickly found his way to the window and leaped out of it, both a joyful and probably terrifying experience for a fat indoor cat. He was recovered promptly but poor Adam’s dad had to experience Duncan’s sneakiness first-hand to really know the power of it all.
