About Us

"There are no bad kitties. Only good kitties with negative attitudes."
- Us


We view the “content landscape” as being vast and unforgiving, like an avalanche of cold gray sludge. We like work that stands apart from the sludge. Sticks with us. Inspires us. Changes us. How ’bout you?


Allow us to introduce ourselves: we’re Negative Kitty, an indie studio headquartered in Brooklyn, New York, with team members all around the US and Canada. When we’re not at work on our own cartoon and media projects, we bring wickedly creative animation and video to artists and brands in need of some visual (and conceptual) edge.

- Est. 2021

- Serving the northeast U.S. & beyond

- Allergic to B.S. (just kidding)

We’ve worked with indie creators, major label music acts, and multimillion dollar companies. Our client work has been featured by publications like The Alternative Press, Brooklyn Vegan, The Tonight Show on NBC, and a whole lot more. 

Frequently Asked Questions

Our work is for artists and brands who need unique visual storytelling that’s hand-crafted to serve their off-kilter audience. Rebellion is a core tenet in our approach to creativity, and we believe that if it doesn’t create impact, it isn’t worth doing. Thinking about going bold? Not sure where to start? Let Negative Kitty help.
