Cat trap.

I have this big box sitting in my living room. Simi decided it would be a great idea to jump in there. SoCo thought it would be an even better idea to hop up and sit on the lids...trapping Simi in the box. He struggled to get out, but she just sat there, occasionally sticking her paws throught the cracks, even poking her nose in there at one point. Then she got bored, turning around to look at me. I was laughing pretty hard at this point. Finally Simi broke free, and looked at me with these big eyes as if to say, "Wtf, mate?!"
