Series Hiatus: On June 2, 2021, the author announced the first hiatus ever in the webcomic to explore a change in his working approach to the strip, promising he would return soon. After a series of comics by guest authors, he did indeed resume the strip on September 24, 2021 here.
Similarly Named Works: In-Universe example, at least in part. The fictional best-selling epic book saga Pridelands, created by Miss Auburn ( Res, actually), which even got some film adaptations, appears in this webcomic. But in Real Life, there's a not very famous series of books written by Jade Buchanan also named Pridelands. While the description of Pridelands from Housepets! sounds like a mix of The Lion King (1994) and A Song of Ice and Fire, Buchanan's Pridelands, while also depicting anthropomorphic lions, seems more focused on erotic and homoerotic romance.
Miscellaneous
Housepets! won the Ursa Major Award for Best Anthropomorphic Comic Strip from 2010 through 2017 inclusive (eight years in a row!), but the streak was broken in 2018, when the comic didn't even get nominated. It would win again in 2019 and 2020.
