My mouse... ):

Question
Her name is Djali. Recently, her left eye seemed to be swelling up, and now it's mostly closed. Also, fur around there is marred and puffed out. She's also making these faint squeaking noise as she breathes. I kinda want to know what's wrong, but I must know how to cure it before anything fatal happens. I already lost another mouse due to starvation. The other mice stole food form her. :/

Answer
Sounds like she has a respiratory infection and needs a vet asap or she may die. It could also be a virus called SDA which is usually fatal, there is no treatment but antibiotics to treat secondary infections can sometimes help them survive as well as syringe feeding with nutritional foods like baby foods or poly aid. Good luck and get to a vet asap
