If you're having trouble reading the solution to this little mindteaser, I'm pretty sure she picked that house because, judging from the perspective, it's a cardboard cutout of a house, and she can just walk around it (but the fact that she's using a crowbar suggests the house was perhaps built at a 90 degree angle to the street, so that the appearance of sexy cat-burglars could be enjoyed by passers-by).
UPDATE: I think I may have to add the comic strip My Cage to my daily rotation; any strip that "borrows" Cassandra Cat is just alright with me.
UPDATE #2: Okay, so apparently My Cage and Slylock Fox share a syndicate (King Features), and Cassandra Cat's appearance in My Cage is a joint effort that will continue all week; presumably, Carla is just filling in the for her absence this week, but we'll hope she remains. Apparently, according to Ed Power, writer of My Cage, My Cage characters were going to appear in Slylock Fox as well, but that aspect got nixed. Which is odd; they couldn't have looked any more out of place than the creatures in this recent police lineup.
