My sister’s cat, Zoe, is probably the dumbest cat I have ever met. That’s okay though, she’s funny sometimes. For example, this morning while we were eating lunch after church, she decided she was going to keep a careful eye on Tarzan the parakeet. Patiently sitting on a nearby table, she watched . . . apparently contemplating how to get into the cage and eat the prey without arousing suspicion. Finally, after a few minutes, she gave up and went back to complaining and making growling and hissing noises at people for no reason.
