Cats appear quite intelligent, but a lot of the behaviors that improve their survivability are instinctive rather than thought out. An example of this is their usual preference 4 drinking moving, rather than standing water.
In my cat's case, this preference has lately become a mania, as she refuses to drink anything except water flowing from the tap. It's got to be a very tiny stream, too; she won't tolerate water that runs too fast and splashes, because too vigorous a flow wets her front paws, & we can't have that.
Feline mistresses are some of the most exacting. This one ought 2 have her own full-time servant.
