This episode was pretty funny. I liked Frit and Frat, since I have these two cats who remind me of them (my little brother LOVES these guys).
As for the ending...
Sad to see my poor boy was absent

. Though my theory to why he wasn't in this episode was not just because they wouldn't be in town (I think), but also because he was sick (and couldn't come to the home by default).
Man, it's been ages since I last saw this episode. Last time was during the middle school in 2008, which was a really dark time of my life.

. I do know, for a fact, that I recorded this episode on it's original airdate (and it works, I checked the tape right after I was done recording), so I should re-watch it.
