Look at This blog has 5 YouTube clips of drunken animals (including monkey, squirrel, cat, dog, elephant, giraffe, warthog, ostrich, wildebeest ...)
The first clip is quite interesting. It's about monkeys at S. Kits who sneakily steal drinks from unsuspecting tourists on the beach.
It tells us that monkey's drinking habit is just like humans: some will do anything for alcohol whereas some are teetotalers who avoid it in favor for soft drinks. Even the percentage is similar: 12% drink regularly in moderation, whereas 5% will drink to the last drop.
