Logan, that's an amazing habit that Mimi has!
My Katz (RIP) always vomited on my bed, during her last years, when she was already sick, she did it almost every day!

Well, maybe you're right and it depends on the fur, Katz' has been shorter but was more fluffy while Luna's is longer and thicker. Maybe she doesn't even develope hair balls in her stomach.
But on the other hand, she has problems with constipation when she's not eating Hill's Hairball Control...
