Squee is everything that Richie isn't. Let me explain...

Richie's huge round eyes are set wide apart; Squee's eyes are small and set near each other.

Richie's ears look ridiculously small when compared to Squee's ridiculously large auricular appendages.

Richie exudes dignity and poise; Squee the ragamuffin never thinks twice about making an absolute fool of himself. Swatting wildly at curtains flapping in the wind, springing up at plastic bags that are far beyond his reach...

Richie is extremely meticulous about cleanliness. I've never seen Squee wash the region beyond the front of his ears. And even after he 'cleans' his face, it's still dirty.

Oh. And Squee still purrs waaaay louder than Richie ever does.
