All Kangaroos Are Left-Handed
JUN 18, 2015 12:00 PM ET // BY JENNIFER VIEGAS
All kangaroos are left-handed, according to new research.
Previously it was thought that “true”-handedness, meaning predictably using one hand over the other, was a feature unique to primates. The new research, published in the journal Current Biology, not only negates that but also goes one step further: kangaroos are even more true-handed than we are.
“According to a special-assessment scale of handedness adopted for primates, kangaroos pulled down the highest grades,” said project leader Yegor Malashichev in a press release. “We observed a remarkable consistency in responses across bipedal species in that they all prefer to use the left, not the right, hand.”
Malashichev, a researcher from Saint Petersburg State University in Russia, and his team observed that wild kangaroos show a natural preference for their left hands when performing particular actions, such as grooming their noses, picking leaves, or bending tree branches. Left-handedness was particularly apparent in eastern grey and red kangaroos.

Glad to read that my fears have been validated.
I bet there are a select few who prefer their right hands, just as there are special humans who prefer their left.
I would always have to take the paper out.
