Felix Busts into Business is a 1925 Felix the Cat short produced by Pat Sullivan.
Plot[]
Felix has a brilliant idea and becomes rich – almost. Felix finds his pockets completely empty and is wondering where his next chicken leg will come from when he suddenly looks out the window into a doctor's office and sees the doctor seeing his patients at the rate of one every two minutes and charging a good sum for each of them.
"Why should he be poor when he can make money this way?" Felix thinks and immediately stuffs himself with a handful of pills and heads off to Africa. Felix's journey across the ocean – which of course he has to swim because he has no money to pay for the passage – is a sequence that should provoke laughter in any theater.
And finally in the jungle, Felix sets up his clinic immediately and at once he has a client. But they are a strange lot, these patients who come to Doctor Felix, and although he is rolling in African money, he lives such a preoccupied existence trying to give pills to giraffes, ostriches and elephants, that before long he gives up his practice, packs up his things, goes home and throws his bag of money out of the doctor's window.
