Science???? Who needs science when you have animal instincts!
Holly the cat didn't let a measly 190 miles separate her from her mama and papa, Bonnie and John Richter.
So the tough tortoiseshell kitty walked all the home!
There's data on birds, turtles and insects, who use magnetic cues, sense of smell, or orientation of the sun to find their way.
Even dogs, though still rare, return home more often, suggesting they have inherited their tracking instincts from wolves, but researchers also state dogs leave the house more often and are easier to spot.
Still, when Holly returned to the Richters, we think they werejust happy to see their kitty back home!
