Recently, Turner Classic Movies showed about a dozen Bobby Bumps films and I was impressed. While the cartoons were silents and a bit primitive compared to later films, for its time, they were very good and hold up pretty well.
In this short, Fido the dog uses a mouse to get to the cat's milk bowl. In the meantime, the mouse and cat run about the house getting into all sorts of mischief.
This short is odd because Bobby is barely in the story. So, instead of seeing this budding sociopath, we see his dog during most of the film....and instead of Bobby being a jerk, the dog clearly is in this one.
As in so many Bobby Bumps films, there is the character of Goldie the maid...who is a very stereotypically drawn black lady. Folks today will likely feel a bit uneasy watching her, though throughout the series Goldie is competent and no dummy. Worth seeing if you love old animated films.
