The cat I grew up with was PETRIFIED of going outside. The one time he managed to sneak out (OH! I HAVE to see what is out there!), about 30 minutes later, he was found clinging to the screen door, shaking and yowling to be let back in!. He never tried to go out again! 😆 We think it was the noises outside (possibly a tractor trailer or something went by or something… we really don’t know!).
