My sisters pet rat Mystery died in her sleep last night. She started her life as a feeder rat for her husbands boa, but like 2 others before her, got lucky because the snake wasn't hungry. They bought her when she was already sick with a respiratory problem, and she was only 3 weeks old. She fought hard for her life for 3 days, and finally passed away while she was sleeping inside her cage in my sisters home last night. R.I.P, little girl. You were a fighter, and now you can be at peace.
