Confirmed: Dogs are smarter than cats

They were tested in three ways, using a single baited string, two parallel strings where only one was baited, and two crossed strings where only one was baited.

The single string test proved no problem, but unlike dogs (which Osthaus has previously tested) no cat consistently chose correctly between two parallel strings. With two crossed strings, one cat always made the wrong choice and others succeeded no more than might be expected by chance.
