they called him amen (1972)

Socrates.
Quirky comic western features a lawyer stroking his pet cat, when he talks to the hero, who has been thrown in jail, and proposes a bank job. "Better put you in your cage Socrates, when I prattle on about robberies you get all excited. I know you!" But Socrates isn't happy being put in the cage, and makes his feelings plain to see.
