The second one is representative of the upper end of what I was getting. It's almost passable, but doesn't hold past about five seconds. The left and right half don't look like they belong to the same animal. The blank space in the middle of the face is huge and detracts from any sense of structure, and the whole mouth area is just odd.
It's seriously impressive for AI, but it's not end-of-artists type stuff. I can google "tiger black and white stencil" and get a bunch of tiger faces, and every one of them is noticeably better. People imagine there are plenty of art jobs where discrepancies like this don't matter, but there really aren't.
I could run pretty much any of these through adobe illustrators auto trace and end up with an amazing vector image.
I could also leave it generating these for an hour and I'd have over 1000 results to choose from.
Again those were my first try and I know nothing about stencil beyond what 2 seconds on Google images could give me. Certainly better than I could produce if you gave me Adobe Illustrator and a weekend. And the image is mine to use as I please, unlike what I could rip off Google Images.
Also, I thought the cat was cute, but there’s really no accounting for taste. Here’s a silly and swirly cat that might be more your thing? This was a cherry picked one of 10 since you have high standards;)

Edit:
I gave this another shot to see if I could get a more complex stencil. This was my very first try again, so truly not cherry picked. Prompt was: “Stencil image of a tiger face. Clip art. Vector art.” This looks like an infinite stencil making machine to me
