...if it was a cat-girl, it seems legit, because they have the human look to them that makes it seem ok, while still retaining that animal's characteristic that charms you.
This, too, falls into the same idea. There are different types of cat-girls, fox-girls, etc.--some have paws, some don't--some have the intelligence of a human, others not--it varies.
But really, it's about something that's meant to be treated with care just not being treated with any care, and removing something instinctive from the restrictions of having to think about it, or consider the consequences of it.
If you've ever been so high as to forget about everything else, it's easy to relate the idea to that. The past and future aren't even considered, just the present moment because the pleasure is overpowering in its raw intensity. That's why I think cat-girls and other types of that sort are so appealing. The mentality is totally different, since it's removed from all of real-life restriction.
