I love cats, however I stand by the assertion this comic makes. While there may not be a substantial body of evidence to prove that cats are dumb, I don't necessarily feel they are winning awards for being clever. In their defense, we don't ask as much from them as dogs. (Westminster Cat Show?) I think a major barrier is their lack of facial expression and distance such ambiguity creates. Perhaps one day the world will see a seeing eye cat, or police feline unit, but until then, just do your best to keep them out of the pool.
Have a great weekend!
