As Kacia noted in her email, this is actually a really nicely made birdhouse. And as anybody who has ever interacted with squirrels knows, the warning is definitely appropriate. It’s the driving force behind so many fabulous inventions (check out the videos for the Whipper, Tipper, and Flipper at Droll Yankees if you don’t believe me).
I’m just concerned that a particularly well-educated squirrel might look at this and say “No squirrel is allowed in there? Clearly the owner of this home was concerned about squirrel-y solitude, as multiple squirrels are welcome. SQUIRREL HOUSE PARTY!”
And as we all know, squirrel house parties are a really bad idea.
