The 1941 Mickey Mouse Cartoon "Lend a Paw" is a re imagining of "Mickey's Pal Pluto" from 1933.
"Mickey's Pal Pluto" from 1933 features Pluto's Angel and Devil for the first time.
The kittens in "Mickey's Pal Pluto" from 1933 bear resemblance to the Orphan kittens in the 1931 Mickey Mouse Cartoon "Mickey's Orphans".
