as a current resident of their natural range, I can confirm this statement.
sorta on topic, today my BP "played with" his food unlike I've ever seen him do before.
f/t adult mouse. he attacked it with malice in his heart (like he almost always does).
squeezed him a lot longer than normal.
then drug him around his habitat. dropping him, then snooping around. pick him up and move him again.
position him into perfect eating position, then just carried and dropped him. tried bring him into his favorite hide. then dragged him back out.
at one point it even looked like he going to try to bury it like a dog would a bone.
he did this for a good 30 minutes before periscoping, taking a glance around, then eating him.
