Mouse went to a performing school where she was training to be an opera singer, but her CVID ( Common Vatiable Immune Difficiency) flared up and left her bed-ridden and unable to leave the house. She requires plasma donations, as her immune system is essentially non-functional. she is getting better, and has been able to work out for little periods on her treadmill, and her muscle atrophy is getting less severe. She recently became Twitch's most subscribed individual, having held a sub-a-thon, in which she donated half the profits ( plus an additional 10,000 dollars) to the Immune Deficiency Foundation. A charity that she has gotten help from in the past.
