Penny's emergency costs

UPDATE: We lost Penny on Sunday, but we still have three thousand dollars left to pay off. Any help is greatly appreciated. We're devastated right now.

Penny and Rosie have been our fur babies for over three years, and they are everything to us. Penny suddenly fell ill on Tuesday and Thursday night, we literally got a life and death call from our local pet ER and drove Penny to Michigan State's veterinary hospital, the only place that can save her. The costs are escalating fast, but we can't just give up on her. We don't want to lose her because we didn't have enough money. Please, anything you can give would be greatly appreciated.
