I also appreciate dogs inability to lie, more, too; it has been my experience that a cat can plot. Dogs have little capacity for thought-out planning, good or bad, and their tail usually gives it away; but a cat gets ideas and a cat that is plotting to shit in your shoes later, and a cat that is more or less indifferent to your existence, or a cat that merely doesn't want to engage with visitors, all look incredibly similar. Much like people, they can be duplicitous and incredibly good at it if they choose to be.

Now, you might appreciate that emotional complexity (and I admit, it does make dogs sound basic by comparison), but I do not. If a dog doesn't like you, you will know almost immediately, almost 100% of the time. They are the worst liars of the domesticated animal kingdom, from being ashamed or not about who pissed on the carpet to whether or not they want you petting them or like the way that you currently are, or if they just get an awful vibe from someone -- I can read them like a book, as someone with mild autism it's fantastic. People? People can fuck themselves. (present company excluded, I suppose, we are in one of the moderately less awful corners of the internet, and I'm guessing the ratio of neurotypicals to not here is somewhat skewed)

I've been around cats (my allergy only developed after a few years around them), and I know from experience they are... wired differently. They're better liars than dogs are, at least, when they want to be. I've met a few cats that obviously liked me, and a couple cats despise me, and just one that I know plotted. Whereas pretty much every dog I've ever met has at least tolerated me if not outright wanted to be my best friend.
