As with last Sunday's strip, this could have been pared down to the last three panels. Unless it an added level of joke that Garfield lost a little dignity by having to struggle with the human-door. I think he gained back his dignity with the fuckin' Reed Richards arm going on in panel 6.
Burning questions:
-Jon's outfit is... what? Is he going night jogging? No, probably not, because he's wearing socks and sandals. And is he wearing an Iowa State sweatshirt with the sleeves cut off?
-Don't the hinges as portrayed in panel 7 indicate that the pet door should swing out in panel 6? Like, in other direction? For that matter, how does Jon's door lock work?
-Is the gag panel at top some kind of ominous reminder that no matter how much you think Garfield is a message just for you, inside it is a REGISTERED TRADEMARK of PAWS, Inc.? This is the only question with an answer. The answer is "yes."
