Recently the author of Hyperbole and a Half wrote about using an online IQ test for her dog, which she worried might be retarded. (Sadly, it turns out that he is.)
I have just come up with an IQ test for both kitten and human:
Hypothesis: A human is smarter than a kitten.
Procedure: Conduct the Chase the Red Laser Dot test many, many, many times.
Results: Knittergran (test human) gives up way, way sooner than does Baxter (four-month old test kitten).
Conclusion: Knittergran is smarter than Baxter.
Therefore: Humans are smarter than kittens.
(And no, I wasn't chasing the dot; Baxter was. Thanks for asking.)
