Cat has distended, leaking stomach, cloudy eyes, fur loss, weight loss

[Sizdian]

I was just told today that my mom's cat has had severe weight loss lately, very noticeable. She also has fur loss in patches, cloudy eyes, and a distended stomach on one side, with some sort of "rust coloured ooze" leaking from her stomach area. I was wondering what might be wrong, she doesn't have enough money to bring the cat in to the vet to check it out.
