"Birds Anonymous," like "Alcoholics Anonymous" is trying to cure an addiction. In this case, it's cats curing their addiction to eating birds. As one bird says in a testimony, "It cost me five houses," however the analogy of "BA" to "AA" really doesn't fit since cats are inbred to go after birds while choosing to drink is just that: a choice.
Nevertheless, it's just a cartoon and a spoof and shows poor Sylvester trying to do the right thing but everywhere he looks and turns, it makes things worse. For instance, he turns on the TV and the first thing he sees is an ad for a tasty bird - a turkey. The announcer says, "Every succulent morsel will simply melt in your mouth...." Listening to this, the poor cat is sweating like Niagara Falls and is tongue is about on the floor. The radio brings more (albeit sadistic) laughs as the music is nothing but songs about birds.
I felt sorry for Sylvester in here. Addiction is brutal and really no laughing matter, whether it's drugs, alcohol or whatever. As some insincere political bigwig once said: "I feel your pain." In here, I felt Sylvester's pain. I've always been in the minority here and rooted for Tweety, but not in this episode. Give the cat a break!
