I had a good "Where's the bunny" panic last week. Went to put the hooligans to bed and no sign of Harley waiting for me as usual. Called him and looked in the run on the grass and no Harley. Called again and turn around; Harley is sitting on the patio looking at me. Little s*d had dug out of one of the runaround linkups at some point.
Luckily he knows the word "pen" and hoped inside his run when I opened the door. Still can't work out how long he'd been running around as I was out at work all day.
