This is the 1950's animated TV version of the "Felix The Cat" cartoon. In this episode called "The Magic Bag", he carries around a Louis Vuitton style bag (Felix must've been pretty wealthy!) that helps him in whatever task he has. Felix needs assistance climbing a high tree, so a ladder is enclosed in the small bag so he can reach the top. A mad scientist type character sees this and tries the snatch the bag away from him. This show is ridiculously cute.
