Help us pay for Pandora's medical costs

We adopted Pandora from the Humane Society in January 2023, because we wanted to give a senior cat her forever home. Unfortunately, since then we've discovered she has had some health issues from when she was a stray. She has had 5 ear infections and now will have to undergo extensive treatment to fix the cause of the issue. This treatment could cost up to $7600 after everything is said and done. She is not eligible for pet insurance, because the ear infections qualify as preexisting condition. Due to my commitments to unpaid work outside of school, I am not able to take a second job in order to pay for her treatment. Any help will be greatly appreciated!
