Cats can be used to judge men. A woman who is looking for a husband should ask the candidate to take her cat to the vet and see how he does it. That's how he very likely will be handling her infants.
My dog, even though it is incredibly stupid and belongs to one of the stupider breeds in general, is capable of easily performing tasks that would be extremely complex for a feline.
How come you don't see any cats at the border, or working in counter narcotics, riot control, security? Because they are useless.
