Who Let the Cats Out?
Cats can be notorious escape artists when they want to get outside. You could probably understand this desire to get out if you are cooped up inside all day too. Cats will take every opportunity given to sneak outside, even if they have to fool you into thinking they have no interest in getting out to make their escape.
Most cat owners are well aware of their cats’ escaping tendencies, which explains why this homeowner left several notes on their door for the maintenance guy. They must have had this problem before with as many notes they had to leave warning the guy about their sneaky cats.
