Feline Follies

When his owner arrives a little while later and sees scraps of food everywhere, she throws Felix out of the house, not knowing it was the mice who did it.

In reaction, Felix runs towards the local gasworks and commits suicide by intentionally inhaling coal gas.

It is a matter of dispute whether to attribute the film and Felix's creation to Sullivan himself, or to Otto Messmer, the studio's lead animator.

Ub Iwerks claimed that he created Mickey Mouse, instead of studio owner Walt Disney.

[1] Feline Follies was not the first short film by the Pat Sullivan Studio to feature a black cat as a protagonist.

A black cat identical in design to Felix in Feline Follies had appeared in promotional materials for the animated short How Charlie Captured the Kaiser (August 1918).

The line art and visual forms of the film were also found to be similar to Pat Sullivan's previous works on comic strips.

[1] Messmer also had a background in comic strips, and he reportedly had a "quite proficient" drawing style, with "well-crafted line work and very convincing volumetric forms".
