I suspect the issue here was confusion around what “it” was as the sentence has two possible subjects - “the cat” and “tail”. Given cat was the primary subject, it probably assumed you wanted the arrow pointing to the cat.
Nah give it a try, I asked 3 AI services to make a cat without a tail, one after several tries gave me an image you couldn’t see where the tail would be (luck)
After, I asked gemini to tell me where the no tailed cats(which had a Tail) tail was… Which is what I got here
You didn’t tell it to point at the tail, so it pointed to it (the cat). Task failed successfully.
I said, can you please draw me a cat without a tail, then I asked this one, it has a tail can you draw an arrow arrow to it. They all had tails
ask for a “manx cat”, they don’t have tails ☞ https://en.wikipedia.org/wiki/Manx_cat
Is this a common thing with AI images so far, it doesn’t know anatomy, just locations of where to draw said names?
