Dogs out, cats in! AI rejects?

Indeed, there is a different moderation success with different moderators, however that is unrelated to cats and dogs and whatever, but is more related to the moderator's experience. My guess is that we have to do with two phenomena:

• Adobe added massively moderators with the high influx of generative art, and those moderators are inexperienced.
• There is a high turnaround in the moderation workforce, creating an even bigger pool of inexperienced workers.

This said, bad quality is bad for everyone, the contributor, Adobe stock and the buyer. Many people (me included) avoid generative art because of the sustained issues with bad quality assets. If you are searching for the right asset for your project, you are investing a lot of time in that search, and the least you need is to have to start over again because the asset prooves being bad as soon as you have licensed the full scale asset. 

I smell spam.

In addition to the malformed limbs, the grass texture is quite odd, more like hair...

Even I can see that the cat is missing a paw...
If it's on topic, then yes, there are a lot of moderators. It feels like some are more critical, others less so. By uploading a large batch of your images, you are more likely to end up with a more critical moderator, and ALL images will be rejected.

Regarding the ideal THEORETICAL image: I'm sure that if you upload your THEORETICAL image (not these 2 images) here that has 100+ purchases and 0 complaints, it will still be criticized to smithereens here. Do not try to prove that your image was rejected due to a moderator's mistake.

P.S. Nonetheless, there are problems in your photo that are obvious to the naked eye, and it is better to delete it before anyone buys it and writes a complaint.

As for your cat:

The question is not, why your dog picture has been refused, but why they accepted your cat picture. Both are awful, I'm sorry to say that.

First for your dog, just by looking at 100% at your asset, I found massively issues:

Well...this particular cat shouldn't have been accepted either. It has no front legs that I can see, other than the deformed one. The dog's feet are also slightly deformed, so they chose correctly on that one.
