They have opposite charges.


A cation is positive (think cute cat videos are a nice positive thing to watch) while anions are negative.

Cations #(+)# are attracted to Cathodes and Anions #(-)# are attracted to Anodes. This means that Cathodes must be negative while Anodes are positive (as opposite charges attract).
