Founder and editor

Jonathan Do

Jonathan Do founded KeepersNook to answer the questions keepers actually ask before they buy an animal: how big it gets, what it costs to house properly, what it can safely eat, and what it can live with. Every guide on this site is written against primary sources and reviewed against the editorial policy.
