What do you do when your cats notoriously run out the front door every time you open it? You put them behind bars, that's what! One man has to turn all his baskets into makeshift cat jails every time he has to open the front door, otherwise, the cats run outside. The cats might hate being locked up, but we bet they appreciate how much their human loves them.
Then, if you put an owl box outside, sometimes you're going to get a few owls. And sometimes, those owls make little owls. One family had an owl box, and when they went to check outside, they found five baby owlets waiting there to greet them. Aw, what cute/ugly/adorable little babies!
