I have a mouse, but they're almost the same on care and requirements.
I would get a saucer wheel for yours, the small size should be good. :3 I have a Silent Spinner, though.
Kaytee is the worst
brand you could possibly get. It contains "Ethoxyquin" which is a preservative that is known to cause cancer in mammals. Get "Brown's Carnival", it's more high quality. I have "Brown's Carnival Hamster & Gerbil" for my mouse because they need a low protein percentage, high protein base foods can cause hot spots. Oxbow should be avoided as well. Link.
She's a cutie, though! I had a Syrian before, his name was Stuffy. lol
