Garfield, the cartoon, debuted in 1978 and has been in circulation since. The strip features a cat named Garfield, a guy named Jon Arbuckle, and Arbuckle’s dog, Odie. Arbuckle is an awkward, perennial bachelor; Odie, a clumsy, good-natured, and not too intelligent drooler; and Garfield, of course, is the lazy, lasagne-loving feline and a bit of a curmudgeon. For most of the cartoon’s life, the three have lived together in comedic bliss. But in October of 1989, that blissful existence was threatened when Garfield woke up to find himself cold and alone.

And then it got really creepy. As seen below, for the five days thereafter, Garfield found himself, alone, in an abandoned house.

The last segment in the series pictured above has Garfield, alone, screaming out in denial — and then, suddenly, Jon and Odie re-appear. In the final frame, Jim Davis, the author of Garfield, writes:

"An imagination is a powerful tool. It can tint memories of the past, shape perceptions of the present, or paint a future so vivid that it can entice . . . or terrify, all depending upon how we conduct ourselves today . . ."

It's a bit dark when you really think about it, especially if you consider what people have speculated that this all means.  Some suggestions have been that the Garfield universe isn’t about a guy, a cat, and a dog, but about the delusions of a pet left alone to fend for himself in what, to him, is a post-Apocalyptic universe. 

As if this isn't enough, there are a few more fan conspiracies, centred around Garfield. If that tickles your interest buds a bit, why don't you click here and here to read more on these?
