I'm Sparrow, an illustrator and genetics nerd located in Iowa. My current day job is tutoring. I launched this website when I was in undergrad and since then I've gained a bit of a reputation as the cat genetics guy. My goal is to eventually branch out to making other types of educational content online.

My pronouns are they/them.

If you'd like to get in touch, the best way to do so would be via my Discord server. I speak more casually there about things I'm working on, and the community is generally a nice place to talk both cats and genetics!

You can also email me, but be warned non-urgent requests have a tendency to get buried in my inbox. If it's been a week without a reply, feel free to send another.
