Leopard can't actually purr. No big cats can purr, except for cheetahs. Cheetahs also chirp to each other, and if you haven't heard it, you should, cause it's adorable.
Yes and no! They can't produce true purrs due to the flexibility of their hyoid bones (the bone that vibrates when small cats purr) but they do produce a similar sound when feeling content

Yes, that is true. Though, leopards actually can't roar as loud as lions and tigers. Also, I would love to have one of these series with a jaguar, but also, one with accurate patterning on it. They are my favorite big cat, and get overlooked and often mistaken as leopards, and that just sucks. Sorry, lol.
Just to let everyone know, chapter 74 is not Canon, and is a draft with different characteristics. Also, it should be noted that it felt like a cut to me, when I noticed Ra was no longer pregnant, and we somehow didn't know how Seth came into Horus' office. So the rape is not canon my dudes.
