Business Cat ran from 2014-2018: it wasn't a continuity strip to begin with, but it developed a main plotline in the middle of the run and the strip stopped when creator Tom Fonder found a natural point in that plotline. It's been nearly a decade since, and it hasn't come back, so I have to assume Fonder is doing different income-generating activities these days. (And, actually, that assumes that a webcomic was income-generating in the first place, which is plausible but not proven.)
The strip was collected, I believe in its entirety, into two books. The first one was Business Cat: Money Power Treats, which I haven't seen. But the book of the back half of the strip, Business Cat: Hostile Takeovers, was available in my library app, so I checked that out recently.
The original concept for the strip was one of those weird juxtapositions: BC is both the CEO of a major global corporation and a cat! So the gags were mostly CEOs doing cat-like things: knocking coffee cups off desks, sitting on employee's laps, demanding skritches during important meetings. As you see from the cover, Fonder drew BC as a human being with a cat head, which made the whole thing quite odd - but humorously so.
Eventually, the worldbuilding got rolling - there are several Business Animals, including BC's nemesis, a pug named Howard. Each of them also runs a global megacorporation, each of them also is an animal in human form (mostly just the head to indicate animal-ness), and, as in so much popular media, they fight - as far as we see, entirely through the mechanisms of capitalism.
BC is not actually a good CEO: that's the central joke. He's easily distracted, unfocused, and doesn't seem to care about anything his company actually does. So it turns out that he replaced their "accountant" - like a lot of fiction about the business world, it has a view of a major corporation as organized like the small business above the chip shop, only in fancier offices - with a plush toy, which led to major irregularities, which led to a visit from the IRS, which led to bankruptcy, oddly described.
Howard sweeps in to "rescue" the company by taking it over, and BC is cast out of the business world, in what was a temporary rebrand of the strip as "The Adventures of Regular Cat." BC lives in an alley, is incarcerated in an animal shelter, finds a new family, and so forth - it gives Fonder a chance to make some pretty familiar cat jokes that didn't fit into the business setting.
Eventually, of course, there is a scheme to get BC back in control of his company and cast out Howard, which of course succeeds, because BC is our hero. And the very last strip comes full circle, repeating the gag from the first strip.
Hostile Takeovers is a fun collection of a crisp, amusing strip that didn't overstay its welcome. I would recommend finding the first book first if you can, but this one has most of the "story" material from the series - and it's not like the concept or background are so complex you need the first book to understand everything.
