Lol, I think it's certainly doable! I have rats, and my cat actually cuddles with them and licks them. (Yeah, I know, not exactly the same thing but!) I don't recommend them being in the same area, because my kitty is just a really good girl. I do, however, recommend MUCH supervision. All cats are different and will respond differently, you'll want to see how your cat(s) react to it.
If you're planning on getting a sugar glider.. Awesome! I'm super jealous!😊
