This question probably has been asked before, but I'll ask anyway: why are the chapters not numbered?
Probably because it doesn't matter in which order you read them. They're only two pages long, and there's no continuing narrative if you read them in a specific order. You know, other than, "my cat maid is so cute when she does X."
Also the fact that they're literally not chapters. This isn't a full manga, just a bunch of Twitter posts. If you ever see a series where every "chapter" is 4 pages or less, it's because it's published on Twitter, which has a limit of four images per Tweet.
