It mostly depends on weight. I can lift my Yorkie by his butt skin and neck skin, and he loves it. If I did that to a heavier animal without loose skin, it would hurt them. Cats tend to lose that extra skin pretty fast. They just like getting squeezed there. (Mostly if they’re hand raised).
Of course everything is context sensitive. You can “scruff” a healthy adult cat without ever hurting them if you do it right. You don’t lift them up by that skin.
