The short "Birds Anonymous", released in 1957, opens with Sylvester once again attempting to catch Tweety, this time succeeding and closing the blinds to hide the evidence. Before he can eat Tweety, however, he is interrupted by an erudite, milquetoast cat (named "Clarence" or "Sam" in some sources but unnamed in the short itself), who tells him that his constant cravings for Tweety are a sign of profound personal weakness, and that the only way for him to overcome this weakness is to kick the habit for good. Believing that he is in need of help, Sylvester proudly joins "Birds Anonymous", a group of cats who have banded together to overcome their addictions to birds.
However, Sylvester's resolve breaks down after a short time, primarily due to constant temptation since he still lives in the same house as Tweety. Sylvester valiantly makes many attempts to control his baser urges, even physically chaining himself to a radiator at one point, but eventually gives in and makes a grab for Tweety, only to be stopped by his cat friend again.
Ashamed of his weakness, Sylvester collapses into sobs, but the cat consoles him, telling him severe withdrawal symptoms are all part of the process, and that if he stays with Birds Anonymous' program, he will eventually succeed and come to love birds, as he does. However, when the cat kisses Tweety to prove his point, years of denial take their toll and the B.A. cat begins laughing maniacally and attempts to devour Tweety himself, this time with Sylvester restraining him and telling him to control himself!
Tweety watches the incident from a kitchen counter and sums up the whole affair with a shrug: "Once a bad ol' puddy tat, always a bad ol' puddy tat!"
