It is a demonstrable fact that dogs know calculus as reported here by The Mathematical Association of America. On the other hand, everyone knows that cats, while obviously intelligent, are too lazy to learn any tricks like all dogs do, at least until they become too old. Therefore, for these two reasons, dogs must be smarter than cats by my reckoning.
But now comes news that felines fathom physics, or at least they naturally grasp the principles of gravity. This conclusion comes from an ingenious experiment on thirty cats done by Japanese researchers. The creatures were found to be inordinately curious about magnetic balls that did not fall out of an overturned metal container. For more details, see this recap by phys.org.
Then to make matters worse for dog lovers like myself, a recent study by a Wisconsin researcher indicates that cat owners are smarter than dog owners. Read it here in Psychology Today and whimper. If it’s any consolation, the study shows that dog people are less neurotic.
“The greatest pleasure of a dog is that you may make a fool of yourself with him, and not only will he not scold you, but he will make a fool of himself, too.”
― Samuel Butler
