Are humans the only animals that get drunk?

No.

Who else likes to get drunk?

A lot of other animals, actually. (See Swedish moose)

Except the pen-tailed treeshrew; they're either the straight edgers of the animal kingdom, or they're the gold standard of the fucntional drunk.

[brownie points for whoever can provide more drunk animal stories]
