Series exploring strange animal behaviour looks at how a surprising number of creatures take substances for pleasure or to cure ailments. Discover starlings that use aromatherapy; chimps that administer their own medicine; an odd amphibian that can heal itself; bee bouncers that stop drunk and disorderly bees returning to the hive; monkeys whose liking for happy hour tells us about our own drinking habits; lemurs that ingest mind-altering millipedes; hedgehogs that indulge in strange rituals; cats that get high on plants; and reindeer whose fondness for magic mushrooms may have spawned the greatest legend of them all.
