Any thoughts on male preds? Butlers or garden workers would fit the theme of the game easily. 
There was also the love interest for Nala. Maybe he could be the fourth book for the bookshelf labeled as envy or lust? 

Other than that, I’d personally enjoy more anal vore content.

heya, me again, just leaving another suggestion since i pretty much have nothing else to do and i think it'd be interesting, basically a massive addition to the unknown ending, where as long as you don't delete the file (same one to end the unknown ending, letting you play the game again), unknown would occasionally pop up on your pc even while the game was closed (kinda like an  invisible program, that you can still close using task manager), kinda like that one goose thing where it'd bring over different pictures and other things, where unknown could like open up text files to talk to you, or even open up small pictures, ofc you'd still be able to close em, i just think it'd be interesting to have, though ik it'd be extremely complex, it'd be like a nice challenge for you to try whenever you're bored or want to challenge yourself, anyways thank you for reading my suggestion, if you do read it at least

I'd love to have more Mika scenes,and for the scene in the basement after her chase,when you give up to have a way to actually have a game over,when you ask for her to have you,instead of being rescue,as well as perhaps...roaming? sort of...like her being at certain open places looking for you.which would make sense instead of not appearing unless sleeping or during scenes only like the left wing timed scene
